This calculator allows you to convert from Second (sidereal) to Second and in a reverse direction. To convert from Second (sidereal) to Second, enter the amount of Second (sidereal) into the first input and to convert from Second to Second (sidereal), enter the amount of Second into the second input.
4 Second (sidereal) = 3.9890782407408 Second
Second (sidereal) to Minute | Second (sidereal) to Hour | Second (sidereal) to Week | Second (sidereal) to Month | Second (sidereal) to Year |4 Second (sidereal) equal 3.9890782407408 Second.
Every 1 Second (sidereal) = 0.99726956018519 Second and so, 4 Second (sidereal) = 4 multiplied by 0.99726956018519 = 3.9890782407408 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:
