Convert time values without memorizing formulas

This Time Unit Converter converts values between nanoseconds, microseconds, milliseconds, seconds, minutes, hours, days, weeks, average months, and average years.

Every calculation uses seconds as a canonical base. The converter multiplies the amount by the source unit factor and divides it by the destination unit factor, providing consistent forward and reverse results.

Fixed units and average calendar units

Nanoseconds through weeks use fixed elapsed-duration factors. Months and years vary on real calendars, so this converter uses the average Gregorian year of 365.2425 days and one twelfth of that value for an average month.
