Dezimalstunden-Konverter

Arbeitszeiten in Dezimalstunden für Gehaltsabrechnung und Rechnungen umwandeln.

H:MM → decimal hours

Colon format H:MM or H:MM:SS; durations over 24 h supported (e.g. 40:30).

Decimal hours → H:MM

Fractions like 7.5, 7.75 or 7.333, rounded to the nearest minute.

Funktionsweise

  1. H:MM → decimal is exact: minutes ÷ 60, so 7:30 is exactly 7.5. Seconds are included as fractions of a minute.
  2. Decimal → H:MM multiplies out to minutes and rounds to the nearest whole minute (0.5 rounds up); the exact value is shown beside the rounded one so nothing is silently lost.
  3. Total minutes are always listed too, the unit most timesheet grids actually use.

Gut zu wissen

  • Payroll systems want decimals because they multiply cleanly by hourly rates; timesheets are read as H:MM but billed in decimals.
  • Values are non-negative durations; negative or invalid inputs are rejected rather than wrapped.
  • For a full shift with breaks, the Work Hours Calculator computes gross and net directly.

Häufig gestellte Fragen

Why do payroll systems want decimal hours?
Decimals multiply cleanly by hourly rates: 7.5 hours × $20 is simple, while 7:30 is not. Timesheets use H:MM but billing uses decimals.
How are fractional minutes handled going decimal → H:MM?
Rounded to the nearest whole minute (0.5 rounds up). The exact value is displayed next to the rounded one, so nothing is silently lost.
Is 7:30 exactly 7.5?
Yes, this direction is exact: minutes ÷ 60. The other direction can involve rounding, which is why the converter always displays both formats.
