About these units

The millisecond (ms) is a unit of time, equal to 0.001 seconds.

The nanosecond (ns) is a unit of time, equal to 1e-9 seconds.

Going the other way, 1 nanosecond = 0.000001 milliseconds. Time conversions look trivial until months and years appear — a month is not 30 days and a year is not 365. This converter uses the astronomical averages (30.44 days and 365.2425 days) so long-range answers stay accurate.
