How the calculation works
- 1 An hour has 60 minutes: divide the minutes by 60 to get the decimal part. 45 minutes = 45 ÷ 60 = 0.75.
- 2 The other way round, multiply the part after the decimal point by 60. 0.75 × 60 = 45 minutes.
- 3 Handy conversions: 10 minutes = 0.17 · 15 = 0.25 · 20 = 0.33 · 30 = 0.50 · 45 = 0.75 · 50 = 0.83.
Frequently asked questions
Why isn't 7:30 the same as 7.30?
Because minutes are base 60 and decimals are base 100: 30 minutes is half an hour, or 0.50 of an hour. So 7:30 is 7.50.
How do I convert 7 hours 45 minutes to decimal hours?
Divide 45 by 60 (0.75) and add it to the hours: 7 + 0.75 = 7.75 hours.
What are decimal hours used for?
To multiply hours by an hourly rate: 7.75 hours × €12 = €93. Multiplying 7.45 (hours and minutes written in a hurry) by €12 would give the wrong amount.
