This calculator allows you to convert from Second to Day (sidereal) and in a reverse direction. To convert from Second to Day (sidereal), enter the amount of Second into the first input and to convert from Day (sidereal) to Second, enter the amount of Day (sidereal) into the second input.
20 Second = 0.00023211525822416 Day (sidereal)
Second to Minute | Second to Hour | Second to Week | Second to Month | Second to Year |20 Second equal 0.00023211525822416 Day (sidereal).
Every 1 Second = 1.1605762911208E-5 Day (sidereal) and so, 20 Second = 20 multiplied by 1.1605762911208E-5 = 0.00023211525822416 Day (sidereal).
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:
