Decimal hours 7.75 h

How it works

decimal = hours + minutes ÷ 60

An hour has 60 minutes, not 100, so 7:45 is 7 hours plus 45 ÷ 60 = 0.75 of an hour: 7.75 hours. Going back, multiply the part after the decimal point by 60 to get the minutes. A common mistake is reading 7.45 hours as 7:45; it’s really 7:27.

  1. Minutes ÷ 60, plus the hours 7:45 → 7.75 h
