Digits kept in the answer. Automatic keeps six, which hides floating-point noise without losing anything real.

Paste one conversion per line, written the way you would say it: "5 km to mi". Handy for a column copied out of a spreadsheet.

About this tool

Converts between units of duration, from nanoseconds to centuries. Months and years are the honest difficulty here: they have no fixed length, so this converter uses the Gregorian averages and says so with the result rather than pretending otherwise.

Questions people actually ask

How long is a month here?
30.436875 days - the average Gregorian month. Real months are 28 to 31 days, so for anything tied to a calendar date use a date calculator instead; this converter is for durations, not dates.
Which year does it use?
The average Gregorian year of 365.2425 days, which is the one that keeps step with the calendar over a long span. The Julian year of exactly 365.25 days is listed separately, because that is the one astronomy uses and the one behind the light-year.
