Convert from hour to nanosecond formula

Total nanosecond = Total hour x 3600000000000

For example, if you want to convert 25 Hour to Nanosecond then,

25 h = 25 x 3600000000000 = 90000000000000 ns

An hour (symbol: h) is a unit of time usually equal 60 minutes. The time of day is typically expressed in English in terms of hours. Whole hours on a 12-hour clock are expressed using the contracted phrase o'clock, from the older of clock.


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.
