This calculator allows you to convert from Millisecond to Second (sidereal) and in a reverse direction. To convert from Millisecond to Second (sidereal), enter the amount of Millisecond into the first input and to convert from Second (sidereal) to Millisecond, enter the amount of Second (sidereal) into the second input.
20 Millisecond = 0.020054758310568 Second (sidereal)
Millisecond to Second | Millisecond to Minute | Millisecond to Hour | Millisecond to Week | Millisecond to Month | Millisecond to Year |20 Millisecond equal 0.020054758310568 Second (sidereal).
Every 1 Millisecond = 0.0010027379155284 Second (sidereal) and so, 20 Millisecond = 20 multiplied by 0.0010027379155284 = 0.020054758310568 Second (sidereal).
What is the second?
The second is an important unit of time. It is the main unit of time in the SI system of units. It can be defined as the time it takes an electromagnetic field to propagate through 3 x 10 5 km of vacuum.
One solar day has 86,400 seconds. There are 60 second per minute.
Second is not small and specific enough to be used by scientists and engineers so smaller units were derived such as:
