This calculator allows you to convert from Second (sidereal) to Nanosecond and in a reverse direction. To convert from Second (sidereal) to Nanosecond, enter the amount of Second (sidereal) into the first input and to convert from Nanosecond to Second (sidereal), enter the amount of Nanosecond into the second input.
1 Second (sidereal) = 997269560.18519 Nanosecond
To convert Second (sidereal) to Nanosecond: Every 1 Second (sidereal) equals 997269560.18519 Nanosecond. For example, 100 Second (sidereal) equal 100 * 997269560.18519 = 99726956018.519 Nanosecond and so on..

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:
