How to convert time durations

1. Enter the duration

   Type the duration in the Value field. Decimals like 1.5 (one and a half) are fine.

2. Pick the source unit

   From offers s (seconds), min (minutes), h (hours), and d (days). All conversions assume an exact 24-hour day.

3. Pick the target unit

   To lists the same units. To convert minutes to hours, leave From as min and switch To to h.

4. Press Run

   Result is computed via seconds as the bridge with 12 significant digits. For calendar months or years use a date calculator instead — this tool does not handle calendar drift.
