You can do the reverse unit conversion from nanosecond to days, or enter any two units below:

days to fortnight

days to millennium

days to decade

days to quarter

days to century

days to minute

days to month

days to millisecond

days to hour

days to second

A continuous period of 24 hours which, unless the context otherwise requires, runs from midnight to midnight.

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.
