Decimal hours = minutes ÷ 60. Payroll systems use decimal hours: 1 h 30 min = 1.5 hours.

30 min = 0.5 h

30 minutes equals 0.5 hours, which is 30 minutes.

Step by step

  1. Divide the minutes by 60: 30 ÷ 60 = 0.5 hours.
  2. The whole number is the hours: 0.
  3. Multiply what is left by 60 to get minutes: 0.5 × 60 = 30.
  4. So 30 minutes = 30 minutes.

How it works

An hour has 60 minutes, so dividing minutes by 60 gives hours. The answer can be written two ways: as decimal hours, which payroll and invoicing systems use (90 minutes = 1.5 hours), or as hours and minutes, which is how we usually say a duration (1 hour 30 minutes). Be careful not to mix the two — 1.5 hours is 1 hour 30 minutes, not 1 hour 50 minutes.
