How it works
Convert time between hours:minutes and decimal hours (for payroll and timesheets).
Enter hours and minutes to get decimal hours and total minutes, or enter decimal hours to recover hours:minutes.
Formula
decimal hours = hours + minutes ÷ 60; total minutes = hours × 60 + minutes.
h- Hours (h)
m- Minutes (0–59) (min)
d- Decimal hours (h)
Examples

Frequently asked questions
Why use decimal hours?
Timekeeping systems often store hours as decimals, so 7 hours 30 minutes becomes 7.5 hours.
Do minutes round up?
No — minutes are converted exactly (÷ 60); no payroll rounding rule is applied.
How to read the result
Decimal hours are the fraction of an hour, so 0.5 equals 30 minutes.
Limitations
Full hours and minutes only; no seconds or fractions of a minute beyond the field limits.
Source: 60 minutes per hour; standard decimal conversion.
