100 Second = 0.027853830986899 Hour (sidereal)
Second to Minute | Second to Hour | Second to Week | Second to Month | Second to Year |100 Second equal 0.027853830986899 Hour (sidereal).
Every 1 Second = 0.00027853830986899 Hour (sidereal) and so, 100 Second = 100 multiplied by 0.00027853830986899 = 0.027853830986899 Hour (sidereal).
What is the second?

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:
