1 s to nanosecond = 1000000000 nanosecond
2 s to nanosecond = 2000000000 nanosecond
3 s to nanosecond = 3000000000 nanosecond
4 s to nanosecond = 4000000000 nanosecond
5 s to nanosecond = 5000000000 nanosecond
6 s to nanosecond = 6000000000 nanosecond
7 s to nanosecond = 7000000000 nanosecond
8 s to nanosecond = 8000000000 nanosecond
9 s to nanosecond = 9000000000 nanosecond
10 s to nanosecond = 10000000000 nanosecond
You can do the reverse unit conversion from nanosecond to s, or enter any two units below:
The second (symbol s) is a unit for time, and one of seven SI base units. It is defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom at zero kelvins.
The SI prefix "nano" represents a factor of 10-9, or in exponential notation, 1E-9.
So 1 nanosecond = 10-9 arcseconds.
The definition of a second is as follows:
A second of arc or arcsecond is a unit of angular measurement which comprises one-sixtieth of an arcminute, or 1/3600 of a degree of arc or 1/1296000 (approximately 7.7×10-7) of a circle. It is the angular diameter of an object of 1 unit diameter at a distance of 360×60×60/(2pi) (approximately 206,265 units), such as (approximately) 1 cm at 2.1 km, or, directly from the definition, 1 astronomical unit at 1 parsec.
