10000 (ten thousand) is the natural number following 9,999 and preceding 10001.

## Name

Many languages have a specific word for this number: in Ancient Greek it is μύριοι (related to the word myriad in English), in Aramaic ܪܒܘܬܐ, in Hebrew רבבה (revava), in Chinese 萬/万 (Mandarin wàn, Cantonese maan6, Hokkien bān), in Japanese 万/萬 [man], in Khmer ម៉ឺន [meun], in Korean 만/萬 [man], in Thai หมื่น [meun], and in Malayalam പതിനായിരം (patinayiram). It is often used to mean an indefinite very large number.[1]

The Greek root was used in early versions of the metric system in the form of the decimal prefix myria-.

The number 10000 can also be written 10,000 (UK and US), 10.000 (Europe mainland), 10 000 (transition metric), or 10•000 (with the dot raised to the middle of the zeroes; metric).

## In time

10000 days can be expressed in these alternative units:

• 864000000 seconds
• 14400000 minutes
