How to convert decimal hours to minutes
A decimal hour is just a fraction of an hour written in base 10. To get minutes back, multiply the decimal part by 60.
Example: 1.5 hours = 1 hour + (0.5 × 60) = 1 hour 30 minutes.
Use the right-hand converter above: type a decimal like 1.5 and it shows 1h 30m. For common values, scan the chart below.
The most-looked-up values, answered directly
0.5 hours is 30 minutes. 0.75 hours is 45 minutes. 0.25 hours is 15 minutes. 0.3 hours is 18 minutes — not 30, because the decimal counts sixtieths of an hour. 1.75 hours is 105 minutes (1 hour 45 minutes), 2.5 hours is 150 minutes (2 hours 30 minutes), and 1.25 hours is 75 minutes (1 hour 15 minutes).
The pattern: multiply the part after the decimal point by 60. Values ending in .25, .50, or .75 come out to the clean quarter hours — 15, 30, and 45 minutes.
