Convert from day to nanosecond formula

Total nanosecond = Total day x 86400000000000

For example, if you want to convert 5 Day to Nanosecond then,

5 d = 5 x 86400000000000 = 432000000000000 ns

The unit of measurement "day" is defined as 86,400 SI seconds and symbolized d. A day is usually 24 hours, plus or minus a possible leap second in Coordinated Universal Time (UTC), and occasionally plus or minus an hour in those locations that change from or to daylight saving time.


A nanosecond (symbol: ns) is an SI unit of time equal to one billionth of a second. Time units ranging between 10−8 and 10−7 seconds are typically expressed as tens or hundreds of nanoseconds.
