How it works

Choose the direction, then enter a duration or decimal hours. Both formats update immediately. This tool handles elapsed time, not times of day. Decimal-to-duration conversion rounds to the nearest minute; displayed decimal hours use up to six decimal places.

Example

7:30 is 7.5 decimal hours. 1.75 hours is 1:45, not 1:75.

Frequently asked questions
