This calculator allows you to convert from Hour (sidereal) to Millisecond and in a reverse direction. To convert from Hour (sidereal) to Millisecond, enter the amount of Hour (sidereal) into the first input and to convert from Millisecond to Hour (sidereal), enter the amount of Millisecond into the second input.
500 Hour (sidereal) = 1795085208.3333 Millisecond
Hour (sidereal) to Second | Hour (sidereal) to Minute | Hour (sidereal) to Hour | Hour (sidereal) to Week | Hour (sidereal) to Month | Hour (sidereal) to Year |500 Hour (sidereal) equal 1795085208.3333 Millisecond.
Every 1 Hour (sidereal) = 3590170.4166667 Millisecond and so, 500 Hour (sidereal) = 500 multiplied by 3590170.4166667 = 1795085208.3333 Millisecond.
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:
