HOW IT WORKS

Why 45 minutes equals 0.75 hours

A clock hour has 60 minutes. To express minutes as part of an hour, divide by 60. For a full duration, add the whole hours.

decimal hours = hours + minutes ÷ 60

For example: 8 hours 45 minutes = 8 + 45 ÷ 60 = 8.75 hours.

To go the other way, keep the whole hours and multiply the decimal part by 60.

minutes = decimal fraction × 60

For example: 4.25 hours = 4 hours + (0.25 × 60 minutes) = 4 h 15 min.

“Industrial minutes” sometimes means hundredths of an hour. One hundredth of an hour is 36 seconds; it is not one ordinary minute.
