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.
2000 Hour (sidereal) = 7180340.8333334 Second
Hour (sidereal) to Minute | Hour (sidereal) to Hour | Hour (sidereal) to Week | Hour (sidereal) to Month | Hour (sidereal) to Year |2000 Hour (sidereal) equal 7180340.8333334 Second.
Every 1 Hour (sidereal) = 3590.1704166667 Second and so, 2000 Hour (sidereal) = 2000 multiplied by 3590.1704166667 = 7180340.8333334 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:
