Why convert hours and minutes to decimal
Payroll systems, invoices, and spreadsheets usually need time worked expressed as a decimal (like 7.75 hours) rather than as hours and minutes (7 hours 45 minutes), since decimals are easier to multiply by an hourly rate.
The formula
Decimal hours = Hours + (Minutes ÷ 60). For example, 45 minutes is 45 ÷ 60 = 0.75, so 7 hours 45 minutes becomes 7.75 decimal hours.
This calculator also shows the equivalent total minutes and seconds for any other conversion you might need.
