Hours to Decimal Converter
Convert hours and minutes into decimal hours for timesheets and payroll.
Time that multiplies cleanly
Timesheets and payroll need time as decimal hours, because a decimal multiplies straight against an hourly rate while hours and minutes do not. This converts a duration in hours and minutes into decimal hours, so seven hours and forty-five minutes becomes 7.75, ready to drop into a spreadsheet or an invoice.
Enter hours and minutes and get the decimal.
The sixty-not-a-hundred trap
The mistake that costs people money is treating minutes as if they were hundredths — writing forty-five minutes as 0.45 of an hour, when it is actually 0.75, because forty-five minutes is three-quarters of an hour. Minutes go up to sixty, not a hundred, so the minutes must be divided by sixty to get the decimal fraction. Do this wrong on every timesheet entry and the small errors compound across a month into real money. The converter handles the division so each entry is billed for exactly the time worked.
Frequently asked questions
Why is 45 minutes 0.75 of an hour, not 0.45?
Because forty-five minutes is three-quarters of an hour. Minutes go to sixty, so you divide by sixty, not treat them as hundredths.
Why convert time to decimal for payroll?
Decimal hours multiply cleanly against an hourly rate, where hours and minutes do not, so timesheets and invoices use decimals.
