Horizontal logarithmic scale marked with units of time

A millisecond (from milli- and second; symbol: ms) is a thousandth (10−3 or 1/1,000) of a second.[1]

10 milliseconds (a hundredth of a second) are called a centisecond, commonly seen on many stopwatches but often mistakenly referred to as milliseconds.

100 milliseconds (one tenth of a second) are called a decisecond.

To help compare orders of magnitude of different times, this page lists times between 10−3 seconds and 100 seconds (1 millisecond and one second). See also times of other orders of magnitude.

Examples in Stock Trading[edit]

In 2002, 85% of all stock market trading happened on the New York Stock Exchange and some human being processed every order.[2] The New York Times estimates that 50 to 70 percent of all trading in 2014 was done by “traders" who live in server parks, i.e. computers running algorithms that execute trades in a fraction of the time that it takes to blink.[3]

Fiber optic cables that start from the Financial District in lower Manhattan and then all the way to Northern New Jersey where 13 public exchanges are located at the Direct Edge Bats Exchange.[4][5]

The largest future exchange in the world is the Chicago Mercantile Exchange,[6] this is where Spread Networks started a 827 mile long fiber optic line, a $300,000,000, 827 mile route to the Bats Exchange in Nortern New Jersey, BATS Trading to be the third largest stock market in the United States, behind the New York Stock Exchange and NASDAQ, all this for a two Millisecond advantage.
