Hours to Minutes
Convert hour to minute instantly — type a value and read the result, with the exact formula shown.
Example
1 h = 60 min, 5 h = 300 min, 10 h = 600 min.
How it works
Minute = Hour × 60. Every value is converted through a single second base unit using internationally defined conversion factors, so any from/to pair stays consistent.
Good to know
Converting hours to minutes is one of the most common everyday calculations, showing up whenever you need to translate a coarse block of time into something more granular. Think of pricing a 2.5-hour service call by the minute, working out how many minutes of audio fit into a 3-hour podcast, billing freelance work, planning interval training, or setting a kitchen or charging timer that only accepts minutes. Because the result is almost always a clean whole number, it's also the conversion people do most often in their heads.
Both units descend from the ancient Babylonian sexagesimal (base-60) system rather than from the metric or imperial traditions. The Babylonians divided things into 60ths because 60 has so many divisors, and that choice survived through Greek astronomy into the clocks we use today. That shared base-60 heritage is exactly why one hour contains 60 minutes and a minute contains 60 seconds — the numbers feel arbitrary only until you know where they come from.
The rule of thumb is simple: multiply hours by 60. To do it mentally, multiply by 6 and add a zero — so 4 hours becomes 24 then 240 minutes. For fractional hours, lean on familiar landmarks: a quarter hour is 15 minutes, a third is 20, a half is 30, and three-quarters is 45. So 2 hours 45 minutes is just 2 × 60 + 45 = 165 minutes.
The most common mistake is treating a decimal hour like an hours-and-minutes reading. "2.5 hours" means 2 hours 30 minutes (150 minutes), but "2.30" on a stopwatch usually means 2 minutes 30 seconds — two very different quantities. When you see a decimal, multiply the whole thing by 60 (2.5 × 60 = 150); don't convert just the fractional part separately and forget the whole hours.

People also ask
How many minutes are in 8 hours?
There are 480 minutes in 8 hours, because 8 × 60 = 480. A standard full-time workday is therefore 480 minutes long.
How do I convert 1.5 hours to minutes?
Multiply 1.5 by 60 to get 90 minutes. The 1 hour gives 60 minutes and the 0.5 gives 30 minutes, totaling 90.
How many minutes is 24 hours?
A full day of 24 hours equals 1,440 minutes, since 24 × 60 = 1,440. That's also 86,400 seconds.
How many minutes are in 2 hours and 30 minutes?
That's 150 minutes: 2 × 60 = 120 minutes, plus the extra 30 minutes equals 150.
What is a quarter of an hour in minutes?
A quarter of an hour is 15 minutes, because 60 ÷ 4 = 15. A half hour is 30 minutes and three-quarters of an hour is 45 minutes.
How do you convert hours to minutes in Excel?
If your value is a plain number of hours in cell A1, use =A1*60 to get minutes. If A1 is a real time value, multiply by 1440 instead, since a day equals 1,440 minutes.
How many minutes is 0.75 hours?
0.75 hours is 45 minutes, because 0.75 × 60 = 45. This is the same as three-quarters of an hour.
Why does one hour equal 60 minutes?
It comes from the ancient Babylonian base-60 (sexagesimal) counting system, which was carried into timekeeping through Greek astronomy. Because 60 divides evenly into many fractions, an hour splits cleanly into halves, thirds, quarters, and fifths.
