Hour to Decimal Converter

How this calculation works

Payroll systems convert clock-form time (hours:minutes) into decimal hours so pay multiplies cleanly. The rule is simple: divide the minutes by 60 and add to the hours.

A quick-reference chart: :15 = 0.25, :30 = 0.5, :45 = 0.75.

How this Hour to Decimal Converter works — 2026 guide

Payroll software hates "7 hours and 45 minutes" — it wants 7.75. The conversion is simple: divide the minutes by 60 and add the hours, so 7:45 becomes 7 + 45/60 = 7.75 hours. This hour to decimal converter does that instantly in both directions and doubles as a payroll rounding tool: under FLSA, employers may round to the nearest 5, 6, or 15 minutes as long as it averages out over time and never consistently shortchanges the employee (29 CFR 785.48). At $20/hour, 7.75 hours × 20 = $155.00 — clean math, accurate pay.

How to use it in 3 steps

1. Enter a clock-form time (HH:MM) to convert to decimal hours — or enter decimal hours to convert the other way.
2. Optionally apply FLSA rounding (5, 6, or 15 minutes) to see how payroll will record the time.
3. Read the decimal hours and, if you add an hourly rate, the exact dollar value.

Who this is for

Hourly employees verifying a timesheet, payroll clerks converting punch data, and managers auditing time records.
