How this tool works
Decimal hours equal total minutes divided by 60. Reverse conversion rounds to the nearest whole minute.
Example
1 hour 30 minutes is 1.50 decimal hours, not 1.30. 1 hour 45 minutes is 1.75.
What this tool does not include
The decimal-hours display is rounded to two decimal places. When converting from a decimal value back to hours and minutes, fractional minutes are rounded to the nearest minute.
Frequently asked questions
