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.
20 Second (sidereal) = 19945391203.704 Nanosecond
Second (sidereal) to Second | Second (sidereal) to Minute | Second (sidereal) to Hour | Second (sidereal) to Week | Second (sidereal) to Month | Second (sidereal) to Year |20 Second (sidereal) equal 19945391203.704 Nanosecond.
Every 1 Second (sidereal) = 997269560.18519 Nanosecond and so, 20 Second (sidereal) = 20 multiplied by 997269560.18519 = 19945391203.704 Nanosecond.
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:
