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.
20 Hour (sidereal) = 71803408333334 Nanosecond
Hour (sidereal) to Second | Hour (sidereal) to Minute | Hour (sidereal) to Hour | Hour (sidereal) to Week | Hour (sidereal) to Month | Hour (sidereal) to Year |20 Hour (sidereal) equal 71803408333334 Nanosecond.
Every 1 Hour (sidereal) = 3590170416666.7 Nanosecond and so, 20 Hour (sidereal) = 20 multiplied by 3590170416666.7 = 71803408333334 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:
