Timesheets often want 7.5 hours, not 7:30. 7 hours 30 minutes is 7.5 decimal hours because 30 ÷ 60 = 0.5. 90 minutes is 1.5 hours. Going the other way, 8.25 hours is 8 hours and 15 minutes — the fraction is always minutes ÷ 60, not a base-100 clock.
Minutes divide by 60, not 100. Overtime multipliers, break deductions, and rounding to the next 15 minutes are employer rules. This converter only changes hours, minutes, and seconds into each other.
It does not apply overtime multipliers, break deductions, or round-to-15-minutes policies — employer rules sit on top of clock math, and time zones belong on the timezone page.
Static conversion factors — not for precision metrology.
7.5. Divide the minutes by 60 and add them to the whole hours. 45 minutes is 0.75, so 7:45 is 7.75 hours.
Instruments apply temperature, calibration, and rounding rules this converter does not. For everyday conversions the factors here are exact; for certification, use calibrated equipment.
Where both exist — such as gallons — the unit list names each, so pick the one you mean.
