500 Second = 0.1392691549345 Hour (sidereal)
Second to Minute | Second to Hour | Second to Week | Second to Month | Second to Year |500 Second equal 0.1392691549345 Hour (sidereal).
Every 1 Second = 0.00027853830986899 Hour (sidereal) and so, 500 Second = 500 multiplied by 0.00027853830986899 = 0.1392691549345 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:
