What this calculator does

The hours calculator converts between "hours and minutes" (e.g. 1 hour 30 minutes) and decimal hours (e.g. 1.5 hours). It works in both directions.

Use it when preparing time sheets, invoices, or schedules that require decimal hours, while you naturally think in hours and minutes.
