ImPACT is the most-widely used and most scientifically validated computerized concussion evaluation system. Many teams and organizations around the world trust ImPACT for concussion management. An estimated 4 to 5 million concussions occur annually, with increases emerging among middle school athletes.
Horizontal logarithmic scale marked with units of time. A millisecond (from milli-and second; symbol: ms) is a thousandth (0.001 or 10 â3 or 1 / 1,000) of a second. 10 milliseconds (a hundredth of a second) are called a centisecond. 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 10â3 seconds and 10 0 seconds (1 milli second and one second). See also times of other orders of magnitude.
There are 1000 milliseconds in a second. 1 Seconds is equal to 1000 Milliseconds. 1 s = 1000 ms. A unit of time known as second is one of the base units of time measurement in SI. In ancient times a second was defined in terms to the duration of a solar day, and in modern times this unit is defined regarding the period of the Earth revolving around the Sun.
