This calculator allows you to convert from Hour (sidereal) to Second and in a reverse direction. To convert from Hour (sidereal) to Second, enter the amount of Hour (sidereal) into the first input and to convert from Second to Hour (sidereal), enter the amount of Second into the second input.
500000 Hour (sidereal) = 1795085208.3333 Second
Hour (sidereal) to Minute | Hour (sidereal) to Hour | Hour (sidereal) to Week | Hour (sidereal) to Month | Hour (sidereal) to Year |500000 Hour (sidereal) equal 1795085208.3333 Second.
Every 1 Hour (sidereal) = 3590.1704166667 Second and so, 500000 Hour (sidereal) = 500000 multiplied by 3590.1704166667 = 1795085208.3333 Second.
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:
