This calculator allows you to convert from Second to Second (sidereal) and in a reverse direction. To convert from Second to Second (sidereal), enter the amount of Second into the first input and to convert from Second (sidereal) to Second, enter the amount of Second (sidereal) into the second input.
20000 Second = 20054.758310568 Second (sidereal)
Second to Minute | Second to Hour | Second to Week | Second to Month | Second to Year |20000 Second equal 20054.758310568 Second (sidereal).
Every 1 Second = 1.0027379155284 Second (sidereal) and so, 20000 Second = 20000 multiplied by 1.0027379155284 = 20054.758310568 Second (sidereal).
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:
