Convert industrial minutes to decimal hours
Industrial minutes (decimal time) are used in working time recording and payroll accounting. Our calculator helps with:
- Payroll accounting: Timesheets in decimal format (1.5h instead of 1:30h)
- Time recording: prepare working hours for ERP systems
- Project billing: Correctly invoice hours worked
- Overtime calculation: Precise time recording for billing
- Time management: SAP, DATEV and other systems use decimal time
Conversion logic: 1 hour = 100 industrial minutes. A normal minute is divided by 0.6:
- 15 minutes = 0.25 hours = 25 industrial minutes
- 30 minutes = 0.50 hours = 50 industrial minutes
- 45 minutes = 0.75 hours = 75 industrial minutes
- 1:30h = 1.5 decimal hours = 150 industrial minutes
The industrial minute makes calculations much easier: 8.5 hours × 15 €/hour = 127.50 € is easier to convert than 8:30h. Modern time recording systems only use decimal format for automated payroll accounting and export to accounting software.
Minutes to decimal hours: table
Time-tracking and payroll systems often record time in decimal hours (also called industrial minutes: 1 hour = 100 units). Divide minutes by 60: 15 minutes = 0.25 h.
