How is the conversion done?

Decimal hours = hours + (minutes / 60). So 90 minutes = 1.5 hours, 1:30 = 1.5.

Can I enter just minutes?

Yes. Enter minutes only (e.g. 90) or HH:MM (e.g. 1:30 or 01:30).

This tool uses hours and minutes only; you can add minutes as decimals (e.g. 1.5 for 1 min 30 sec) if needed.

Convert minutes to decimal hours, or HH:MM time to decimal hours (e.g. 90 min → 1.5, 1:30 → 1.5).
