1/ 100 seconds, in order to accurately time. Ms is 1/1000 of a second, microseconds is 1/1000000 of a second.
Stopwatch is a common measuring instrument. Can say again "stop watch." consists of a pause button, electronic screen, etc.
It is the use of the isochronous control pointer rotation and timing. , on the table there is a table over there is a button on the. Turn button, wind, this is the power of walking a stopwatch.

(note: use this stopwatch must complete this process to the next time. This kind of table can't again to start the stopwatch continuous after press stop timing. In order to solve this problem, some stopwatch with a button on the left on the table, when the table about pushing the button up, stop running; push down, or continue to cumulative time.)
The precision of the stopwatch is in commonly 0.1 0.2 seconds stopwatch and 0.01 to 0.01, and 0.001 to 0.002 a stopwatch, timing error is the main table is not allowed, stop watch. Stopwatch before using the wind-up shoulds not be too tight, so as to avoid rupture. After using the table should be start, make a clockwork completely let go.
