Time-to-Decimal Calculator

Convert a duration entered as whole hours and minutes into decimal hours, a common format for timesheets, payroll and billing. The calculator divides the minute portion by 60 rather than appending it after a decimal point, then adds the resulting fraction to the whole hours. It also shows total minutes as a simple cross-check. The output is a duration conversion only; it does not calculate wages, overtime premiums, rounding policy or billable increments.

How it is calculated

Enter the whole hours and remaining minutes.

Confirm the minute value is from 0 through 59.

Use decimal hours for a timesheet or total minutes for a duration cross-check.

Formula

Decimal hours: whole hours + minutes ÷ 60

Total minutes: whole hours × 60 + minutes
