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.
500000 Millisecond = 0.1392691549345 Hour (sidereal)
Millisecond to Second | Millisecond to Minute | Millisecond to Hour | Millisecond to Week | Millisecond to Month | Millisecond to Year |500000 Millisecond equal 0.1392691549345 Hour (sidereal).
Every 1 Millisecond = 2.7853830986899E-7 Hour (sidereal) and so, 500000 Millisecond = 500000 multiplied by 2.7853830986899E-7 = 0.1392691549345 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:
