English number words include numerals and various words derived from them, as well as a large number of words borrowed from other languages.
|2||two||12||twelve (a dozen)||20||twenty (a score)|
|4||four||14||fourteen||40||forty (no "u")|
|5||five||15||fifteen (note "f", not "v")||50||fifty (note "f", not "v")|
|8||eight||18||eighteen (only one "t")||80||eighty (only one "t")|
|9||nine||19||nineteen||90||ninety (note the "e")|
If a number is in the range 21 to 99, and the second digit is not zero, one typically writes the number as two words separated by a hyphen.
In English, the hundreds are perfectly regular, except that the word hundred remains in its singular form regardless of the number preceding it.
So too are the thousands, with the number of thousands followed by the word "thousand"
|10,000||ten thousand or (rarely used) a myriad|
|100,000||one hundred thousand or one lakh (Indian English)|
|999,000||nine hundred and ninety-nine thousand (inclusively British English, Irish English, Australian English, and New Zealand English)
nine hundred ninety-nine thousand (American English)
|10,000,000||ten million or one crore (Indian English)|
In American usage, four-digit numbers with non-zero hundreds are often named using multiples of "hundred" and combined with tens and ones: "One thousand one", "Eleven hundred three", "Twelve hundred twenty-five", "Four thousand forty-two", or "Ninety-nine hundred ninety-nine." In British usage, this style is common for multiples of 100 between 1,000 and 2,000 (e.g. 1,500 as "fifteen hundred") but not for higher numbers.
Americans may pronounce four-digit numbers with non-zero tens and ones as pairs of two-digit numbers without saying "hundred" and inserting "oh" for zero tens: "twenty-six fifty-nine" or "forty-one oh five". This usage probably evolved from the distinctive usage for years; "nineteen-eighty-one", or from four-digit numbers used in the American telephone numbering system which were originally two letters followed by a number followed by a four-digit number, later by a three-digit number followed by the four-digit number. It is avoided for numbers less than 2500 if the context may mean confusion with time of day: "ten ten" or "twelve oh four".
Intermediate numbers are read differently depending on their use. Their typical naming occurs when the numbers are used for counting. Another way is for when they are used as labels. The second column method is used much more often in American English than British English. The third column is used in British English but rarely in American English (although the use of the second and third columns is not necessarily directly interchangeable between the two regional variants). In other words, British English and American English can seemingly agree, but it depends on a specific situation (in this example, bus numbers).
|Common British vernacular||Common American vernacular||Common British vernacular|
|"How many marbles do you have?"||"What is your house number?"||"Which bus goes to the high street?"|
|101||"A hundred and one."||"One-oh-one."
Here, "oh" is used for the digit zero.
|109||"A hundred and nine."||"One-oh-nine."||"One-oh-nine."|
|110||"A hundred and ten."||"One-ten."||"One-one-oh."|
|117||"A hundred and seventeen."||"One-seventeen."||"One-one-seven."|
|120||"A hundred and twenty."||"One-twenty."||"One-two-oh", "One-two-zero."|
|152||"A hundred and fifty-two."||"One-fifty-two."||"One-five-two."|
|208||"Two hundred and eight."||"Two-oh-eight."||"Two-oh-eight."|
|334||"Three hundred and thirty-four."||"Three-thirty-four."||"Three-three-four."|
Note: When writing a cheque (or check), the number 100 is always written "one hundred". It is never "a hundred".
In American English, many students are taught not to use the word and anywhere in the whole part of a number, so it is not used before the tens and ones. It is instead used as a verbal delimiter when dealing with compound numbers. Thus, instead of "three hundred and seventy-three", one would say "three hundred seventy-three". For details, see American and British English differences.
For numbers above a million, there are two different systems for naming numbers in English (for the use of prefixes such as kilo- for a thousand, mega- for a million, milli- for a thousandth, etc. see SI units):
- the long scale (decreasingly used in British English) designates a system of numeric names in which a thousand million is called a ‘‘milliard’’ (but the latter usage is now rare), and ‘‘billion’’ is used for a million million.
- the short scale (always used in American English and increasingly in British English) designates a system of numeric names in which a thousand million is called a ‘‘billion’’, and the word ‘‘milliard’’ is not used.
|Short scale||Long scale||Indian
(or South Asian) English
|1,000,000||106||one million||one million||ten lakh|
a thousand million
a thousand million
|one hundred crore
a thousand billion
a million million
|one lakh crore
a thousand trillion
a thousand billion
|ten crore crore
a thousand quadrillion
a million billion
|ten thousand crore crore
a thousand quintillion
a thousand trillion
|one crore crore crore|
The numbers past a trillion in short scale system, in ascending powers of ten, are as follows: quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion, undecillion, duodecillion, tredecillion, quattuordecillion, and quindecillion (that's 10 to the 48th, or a one followed by 48 zeros). The highest number listed on Robert Munafo's table, is a milli-millillion. That's 10 to the 3000003rd.
Although British English has traditionally followed the long-scale numbering system, the short-scale usage has become increasingly common in recent years. For example, the UK Government and BBC websites use the newer short-scale values exclusively.
The terms arab, kharab, padm and shankh are more commonly found in old sections of Indian Mathematics.
Here are some approximate composite large numbers in American English:
|1,200,000||1.2 million||one point two million|
|3,000,000||3 million||three million|
|250,000,000||250 million||two hundred fifty million|
|6,400,000,000||6.4 billion||six point four billion|
|23,380,000,000||23.38 billion||twenty-three point three eight billion|
Often, large numbers are written with (preferably non-breaking) half-spaces or thin spaces separating the thousands (and, sometimes, with normal spaces or apostrophes) instead of commas—to ensure that confusion is not caused in countries where a decimal comma is used. Thus, a million is often written 1 000 000.
A few numbers have special names (in addition to their regular names):
- 0: has several other names, depending on context:
- zero: formal scientific usage
- naught / nought: mostly British usage
- aught: Mostly archaic but still occasionally used when a digit in mid-number is 0 (as in "thirty-aught-six", the .30-06 Springfield rifle cartridge and by association guns that fire it)
- oh: used when spelling numbers (like telephone, bank account, bus line [British: bus route])
- nil: in general sport scores, British usage ("The score is two–nil.")

- null: used technically to refer to an object or idea related to nothingness. The 0th aleph number () is pronounced "aleph-null".
- love: in tennis, badminton, squash and similar sports (origin disputed, often said to come from French l'œuf, "egg"; but the Oxford English Dictionary mentions the phrase for love, meaning nothing is at risk)
- zilch, nada (from Spanish), zip: used informally when stressing nothingness; this is true especially in combination with one another ("You know nothing—zero, zip, nada, zilch!"); American usage

- 12: a dozen (first power of the duodecimal base), used mostly in commerce
- 13: a baker's dozen
- 20: a score (first power of the vigesimal base), nowadays archaic; famously used in the opening of the Gettysburg Address: "Four score and seven years ago..." The Number of the Beast in the King James Bible is rendered "Six hundred threescore and six". Also in The Book of Common Prayer, Psalm 90 as used in the Burial Service - "The days of our age are threescore years and ten; ...."
- 50: half a century, literally half of a hundred, usually used in cricket scores. Normally referred to as a 'half-century' without the 'a'.

- 10googolplex: googolplexplex (1 followed by a googolplex of zeros)
Combinations of numbers in most sports scores are read as in the following examples:
- 1–0 British English: one-nil; American English: one-nothing, one-zip, or one-zero
- 0–0 British English: nil-nil, or more rarely nil all; American English: zero-zero or nothing-nothing, (occasionally scoreless or no score)
- 2–2 two-two or two all; American English also twos, two to two, even at two, or two up.
Naming conventions of Tennis scores (and related sports) are different from other sports.
A few numbers have specialised multiplicative numbers expresses how many times some event happens (adverbs):
Compare these specialist multiplicative numbers to express how many times some thing exists (adjectives):
Other examples are given in the Specialist Numbers.
The name of a negative number is the name of the corresponding positive number preceded by "minus" or (American English) "negative". Thus −5.2 is "minus five point two" or "negative five point two". For temperatures, North Americans colloquially say "below" — short for "below zero" — so a temperature of −5° is "five below" (in contrast, for example, to "two above" for 2°, occasionally used for emphasis when referring to several temperatures or ranges both positive and negative. This is particularly common in Canada where the use of Celsius in weather forecasting means that temperatures can regularly drift above and below zero at certain times of year.)

Ordinal numbers refer to a position in a series. Common ordinals include:
|0th||zeroth or noughth (see below)||10th||tenth|
|2nd||second||12th||twelfth (note "f", not "v")||20th||twentieth|
|8th||eighth (only one "t")||18th||eighteenth||80th||eightieth|
|9th||ninth (no "e")||19th||nineteenth||90th||ninetieth|
Ordinal numbers such as 21st, 33rd, etc., are formed by combining a cardinal ten with an ordinal unit.
Higher ordinals are not often written in words, unless they are round numbers (thousandth, millionth, billionth). They are written using digits and letters as described below. Here are some rules that should be borne in mind.
- The suffixes -th, -st, -nd and -rd are occasionally written superscript above the number itself.
- If the tens digit of a number is 1, then write "th" after the number. For example: 13th, 19th, 112th, 9,311th.
- If the tens digit is not equal to 1, then use the following table:
|If the units digit is:||0||1||2||3||4||5||6||7||8||9|
|write this after the number||th||st||nd||rd||th||th||th||th||th||th|
- For example: 2nd, 7th, 20th, 23rd, 52nd, 135th, 301st.
These ordinal abbreviations are actually hybrid contractions of a numeral and a word. 1st is "1" + "st" from "first". Similarly, "nd" is used for "second" and "rd" for "third". In the legal field and in some older publications, the ordinal abbreviation for "second" and "third" is simply "d".
- For example: 42d, 33d, 23d.
NB: The practice of using "d" to denote "second" and "third" is still often followed in the numeric designations of units in the US armed forces, for example, 533d Squadron.
Any ordinal name that doesn't end in "first", "second", or "third", ends in "th".
There are a number of ways to read years. The following table offers a list of valid pronunciations and alternate pronunciations for any given year of the Gregorian calendar.
|Year||Most common pronunciation method||Alternative methods|
|1 BC||(The year) One Before Christ (BC)||1 before the Common era (BCE)|
|1||(The year) One Anno Domini (AD)||of the Common era (CE)
In the year of Our Lord 1
Two hundred (and) thirty-five
Nine hundred (and) eleven
Nine hundred (and) ninety-nine
|1000||One thousand||Ten hundred
|1004||One thousand (and) four||Ten oh-four|
|1010||Ten ten||One thousand (and) ten|
|1050||Ten fifty||One thousand (and) fifty|
One thousand, two hundred (and) twenty-five
|1900||Nineteen hundred||One thousand, nine hundred
|1901||Nineteen oh-one||Nineteen hundred (and) one
One thousand, nine hundred (and) one
Nineteen aught one
|1919||Nineteen nineteen||Nineteen hundred (and) nineteen
One thousand, nine hundred (and) nineteen
|1999||Nineteen ninety-nine||Nineteen hundred (and) ninety-nine
One thousand, nine hundred (and) ninety-nine
|2000||Two thousand||Twenty hundred
|2001||Two thousand (and) one||Twenty oh-one
Twenty hundred (and) one
|2009||Two thousand (and) nine||Twenty oh-nine
Twenty hundred (and) nine
|2010||Two thousand (and) ten
Twenty ten 
|Twenty hundred (and) ten
Fractions and decimals
In spoken English, ordinal numbers are also used to quantify the denominator of a fraction. Thus "fifth" can mean the element between fourth and sixth, or the fraction created by dividing the unit into five pieces. In this usage, the ordinal numbers can be pluralized: one seventh, two sevenths. The sole exception to this rule is division by two. The ordinal term "second" can only refer to location in a series; for fractions English speakers use the term 'half' (plural "halves").
|1/10 or 0.1||one tenth|
|2/10 or 0.2||two tenths|
|1/4||one quarter or (mainly American English) one fourth|
|3/10 or 0.3||three tenths|
|4/10 or 0.4||four tenths|
|6/10 or 0.6||six tenths|
|7/10 or 0.7||seven tenths|
|3/4||three quarters or three fourths|
|8/10 or 0.8||eight tenths|
|9/10 or 0.9||nine tenths|
Alternatively, and for greater numbers, one may say for 1/2 "one over two", for 5/8 "five over eight", and so on. This "over" form is also widely used in mathematics.
Numbers with a decimal point may be read as a cardinal number, then "and", then another cardinal number followed by an indication of the significance of the second cardinal number (mainly U.S.); or as a cardinal number, followed by "point", and then by the digits of the fractional part. The indication of significance takes the form of the denominator of the fraction indicating division by the smallest power of ten larger than the second cardinal. This is modified when the first cardinal is zero, in which case neither the zero nor the "and" is pronounced, but the zero is optional in the "point" form of the fraction.
- 0.002 is "two thousandths" (mainly U.S.); or "point zero zero two", "point oh oh two", "nought point zero zero two", etc.
- 3.1416 is "three point one four one six"
- 99.3 is "ninety-nine and three tenths" (mainly U.S.); or "ninety-nine point three".
In English the decimal point was originally printed in the center of the line (0·002), but with the advent of the typewriter it was placed at the bottom of the line, so that a single key could be used as a full stop/period and as a decimal point. In many non-English languages a full-stop/period at the bottom of the line is used as a thousands separator with a comma being used as the decimal point.
Fractions together with an integer are read as follows:
- 1 1/2 is "one and a half"
- 6 1/4 is "six and a quarter"
- 7 5/8 is "seven and five eighths"
A space is required between the whole number and the fraction; however, if a special fraction character is used like "½", then the space can be done without, e.g.
- 9 1/2
Whether to use digits or words
With very little deviation, most grammatical texts rule that the numbers zero to nine inclusive should be "written out" – meaning instead of "1" and "2", one would write "one" and "two".
- Example: "I have two apples." (Preferred)
- Example: "I have 2 apples."
After "nine", one can head straight back into the 10, 11, 12, etc., although some write out the numbers until "twelve".
- Example: "I have 28 grapes." (Preferred)
- Example: "I have twenty-eight grapes."
Another common usage is to write out any number that can be expressed as one or two words, and use figures otherwise.
- "There are six million dogs." (Preferred)
- "There are 6,000,000 dogs."
- "That is one hundred and twenty-five oranges." (British English)
- "That is one hundred twenty-five oranges." (US-American English)
- "That is 125 oranges." (Preferred)
Numbers at the beginning of a sentence should also be written out.
The above rules are not always used. In literature, larger numbers might be spelled out. On the other hand, digits might be more commonly used in technical or financial articles, where many figures are discussed. In particular, the two different forms should not be used for figures that serve the same purpose; for example, it is inelegant to write, "Between day twelve and day 15 of the study, the population doubled."
Colloquial English has a small vocabulary of empty numbers that can be employed when there is uncertainty as to the precise number to use, but it is desirable to define a general range: specifically, the terms "umpteen", "umpty", and "zillion". These are derived etymologically from the range affixes:
- "-teen" (designating the range as being between 10 and 20)
- "-ty" (designating the range as being in one of the decades between 20 and 100)
- "-illion" (designating the range as being above 1,000,000; or, more generally, as being extremely large).
The prefix "ump-" is added to the first two suffixes to produce the empty numbers "umpteen" and "umpty": it is of uncertain origin. There is a noticeable absence of an empty number in the hundreds range.
Usage of empty numbers:
- The word "umpteen" may be used as an adjective, as in "I had to go to umpteen stores to find shoes that fit." It can also be used to modify a larger number, usually "million", as in "Umpteen million people watched the show; but they still cancelled it."
- "Umpty" is not in common usage. It can appear in the form "umpty-one" (parallelling the usage in such numbers as "twenty-one"), as in "There are umpty-one ways to do it wrong." "Umpty-ump" is also heard, though "ump" is never used by itself.
- The word "zillion" may be used as an adjective, modifying a noun. The noun phrase normally contains the indefinite article "a", as in "There must be a zillion sites on the World Wide Web."
- The plural "zillions" designates a number indefinitely larger than "millions" or "billions". In this case, the construction is parallel to the one for "millions" or "billions", with the number used as a plural count noun, followed by a prepositional phrase with "of", as in "Out in the countryside, the night sky is filled with zillions of stars."
- Empty numbers are sometimes made up, with obvious meaning: "squillions" is obviously an empty, but very large, number; a "squintillionth" would be a very small number.
- Some empty numbers may be modified by actual numbers, such as "four zillion", and are used for jest, exaggeration, or to relate abstractly to actual numbers.
- Empty numbers are colloquial, and primarily used in oral speech or informal contexts. They are inappropriate in formal or scholarly usage.
