This calculator allows you to convert from Hour (sidereal) to Nanosecond and in a reverse direction. To convert from Hour (sidereal) to Nanosecond, enter the amount of Hour (sidereal) into the first input and to convert from Nanosecond to Hour (sidereal), enter the amount of Nanosecond into the second input.
1 Hour (sidereal) = 3590170416666.7 Nanosecond
To convert Hour (sidereal) to Nanosecond: Every 1 Hour (sidereal) equals 3590170416666.7 Nanosecond. For example, 100 Hour (sidereal) equal 100 * 3590170416666.7 = 3.5901704166667E+14 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:
