Time arithmetic with hours and minutes

Converts hours (and fractions of hours) to minutes, or minutes to hours. Commonly needed for payroll calculations, scheduling, time-tracking systems, and unit conversions in physics and engineering.

💡

Tip: For payroll: always convert decimal hours to h:mm before manually calculating pay. 8.83 hours × $15 = $132.45, but the employee worked 8h 50m, not 8h 83m.

  1. 1Hours to minutes: multiply by 60
  2. 2Minutes to hours: divide by 60
  3. 3Decimal hours to h:mm: integer part = hours, decimal × 60 = minutes
  4. 42.75 hours = 2 hours and 0.75×60 = 45 minutes = 2:45

Fun Fact

Timesheet software often records hours as decimals (8.5 hours) while scheduling software uses h:mm (8:30). Converting between the two is a surprisingly common source of payroll errors — 8 hours 50 minutes ≠ 8.5 hours.
