This calculator allows you to convert from Millisecond to Hour (sidereal) and in a reverse direction. To convert from Millisecond to Hour (sidereal), enter the amount of Millisecond into the first input and to convert from Hour (sidereal) to Millisecond, enter the amount of Hour (sidereal) into the second input.
20000 Millisecond = 0.0055707661973799 Hour (sidereal)
Millisecond to Second | Millisecond to Minute | Millisecond to Hour | Millisecond to Week | Millisecond to Month | Millisecond to Year |20000 Millisecond equal 0.0055707661973799 Hour (sidereal).
Every 1 Millisecond = 2.7853830986899E-7 Hour (sidereal) and so, 20000 Millisecond = 20000 multiplied by 2.7853830986899E-7 = 0.0055707661973799 Hour (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:
