Convert decimal hours into hours, minutes and seconds — the reverse of decimal time, ready for rosters and timesheets.
To convert decimal hours to time, keep the whole number as the hours, then multiply the part after the decimal point by 60 to get the minutes. For example, 7.5 hours is 7 hours and 0.5 × 60 = 30 minutes, so 7.5 = 7 hours 30 minutes. Remember that 7.50 does not mean 7 hours 50 minutes — the decimal is a fraction of an hour, not minutes. This calculator shows every step.
Type a decimal number of hours, such as 7.5 or 8.25. Choose Hours & minutes for a rounded time, or Hours, min & sec when you need seconds as well. Press Convert to see the answer and the working, then use Copy result to paste it into a roster, email or invoice. Values over 24 hours and negative values are both handled.
Split the number at the decimal point. The whole part is the hours. Multiply the fractional part by 60 to turn it into minutes. If you want seconds too, multiply whatever is left over by 60 again.
= hours× 60 = minutes× 60 = seconds= 15 min 0.5 = 30 min 0.75 = 45 min= 6 min 0.2 = 12 min 0.9 = 54 min

Turning decimal hours back into time is common wherever a payroll or tracking system stores hours as a decimal but people think in hours and minutes: reading a timesheet total, checking a payslip, setting a roster, planning shifts, quoting a job in real time, and reconciling billed hours on an invoice. It is the everyday partner of the Time to Decimal Calculator.
Payroll systems usually store worked time as decimal hours because it is easy to multiply by a pay rate. To show that time on a payslip, roster or timesheet, they convert it back the way this calculator does: the whole number stays as the hours and the decimal part is multiplied by 60 for the minutes. A stored value of 38.25 hours becomes 38 hours 15 minutes on the roster, while 7.5 hours prints as 7 h 30 min.
This reverse conversion is handy for checking a payslip against the hours you actually worked, reading a rostered shift length, or turning a billed decimal figure back into real time for a client. Employers and payroll software may round to the nearest minute in different ways, so always follow your employer's or payroll system's requirements.
