This calculator allows you to convert from Second (sidereal) to Millisecond and in a reverse direction. To convert from Second (sidereal) to Millisecond, enter the amount of Second (sidereal) into the first input and to convert from Millisecond to Second (sidereal), enter the amount of Millisecond into the second input.
500 Second (sidereal) = 498634.78009259 Millisecond
Second (sidereal) to Second | Second (sidereal) to Minute | Second (sidereal) to Hour | Second (sidereal) to Week | Second (sidereal) to Month | Second (sidereal) to Year |500 Second (sidereal) equal 498634.78009259 Millisecond.
Every 1 Second (sidereal) = 997.26956018519 Millisecond and so, 500 Second (sidereal) = 500 multiplied by 997.26956018519 = 498634.78009259 Millisecond.
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:
