About Time Unit Converter

Convert durations between milliseconds, seconds and larger time units.

Enter a value in a unit field or paste a supported duration, then read the equivalent values.

Copy the unit breakdown for a timeout, media duration or planning estimate.

The calculation or rendering runs in this browser tab. Copy, download and share actions make the chosen output available outside this tab.

Scope and limits

  • Only finite values produce a result. Month/year duration ratios are fixed approximations from the duration library; they are not calendar-date arithmetic.

Frequently asked questions

Is one month always a fixed number of days?
Calendar months differ. Use Date Calculator to add months to a real date, rather than using an approximate duration ratio.
