Hours to Minutes Calculator
Turn a duration like 2 hours 15 minutes into a single total minutes value instantly. Built for anywhere that only takes one minutes field, like countdown timers or runtime listings, with no sign-up required.
Hours and minutes ⇄ minutes
2 hr 30 min = 150 minutes

How it works
Enter hours and minutes
Type a number of hours and minutes, like 2 hours 30 minutes, into the fields.
Read the total minutes
The total minutes field updates instantly, with no button to press.
Or start from total minutes
Type a total minutes value instead, and the hours and minutes fields fill in automatically.
Hours to minutes, or hours to decimal
Both convert the same duration, but into two different formats, and it's worth checking which one the field in front of you actually expects.
A whole minutes total
2 hours 30 minutes becomes 150, a whole number with nothing left over. This is what a countdown timer, a video runtime field, or a kitchen timer expects.
A decimal hour
2 hours 30 minutes becomes 2.5, a fraction of an hour. This is what a payroll, invoicing, or timesheet system expects; use the hours to decimal calculator for that instead.
How to convert hours to minutes
Multiply the hours by 60, then add any leftover minutes: hours to minutes is hours × 60 + minutes. A 2 hour 15 minute movie becomes 2 × 60 + 15 = 135 minutes for a cinema listing. A 1 hour 45 minute bake time becomes 105 minutes for a kitchen timer that only accepts one field. The calculator above does this instantly as you type.
The multiplication only applies to the hours. It's a common slip to multiply the whole duration by 60, which would turn 2 hours 30 minutes into 150 minutes and then 30 more on top by mistake. Only the hours get multiplied; the minutes are added once, unchanged.
Where hours to minutes shows up
Anywhere a tool only accepts a single minutes field, a duration written as hours and minutes has to be converted first before it will be accepted.
Video & podcast editing
Editing software and cinema listings show a runtime as a single minutes figure, like 135 min, rather than 2h 15m.
Kitchen timers
Most kitchen timers accept one minutes field, so a recipe step written as 1 hour 45 minutes has to become 105 before you can set it.
Meeting & event scheduling
Calendar and booking tools that store an event's length in minutes need a duration like 1 hour 30 minutes converted to 90 before it can be entered.
Common hours to minutes values
Typical durations and their total minutes equivalents.

Common mistakes converting hours to minutes
The formula is simple, but a few habits still produce the wrong total.
Multiplying the hours but forgetting the minutes
2 hours 30 minutes is not just 2 × 60 = 120. The 30 leftover minutes still have to be added on top, for a total of 150.
Confusing total minutes with a decimal hour
135 minutes and 1.35 hours are not the same duration. 135 minutes is 2.25 decimal hours (135 ÷ 60), so swapping the two figures gives a result that's off by almost an hour.
Assuming a minutes field caps at 59
Unlike a clock display, a total minutes field has no upper limit. A 195 minute movie is a perfectly valid value; there's no need to convert it to hours first.
Dropping seconds before converting
If a duration includes seconds, like 1 hour 30 minutes 45 seconds, rounding the seconds away before converting can shift the final minutes total by up to a minute.
Frequently asked questions
Common questions about converting between decimal hours and minutes.
What is a convert hours to minutes calculator?
A convert hours to minutes calculator turns hours and minutes, like 2 hours 30 minutes, into a single total minutes value, like 150 minutes. It's a plain duration converter, with no decimal hours involved.
How many minutes is 2 hours 15 minutes?
2 hours 15 minutes is 135 minutes (2 × 60 = 120, plus 15, is 135).
How many minutes is 1 hour?
1 hour is 60 minutes.
How many minutes is 8 hours?
8 hours is 480 minutes (8 × 60 = 480).
How do I convert hours to minutes?
Multiply the number of hours by 60, then add any extra minutes. For example, 2 hours 30 minutes: 2 × 60 = 120, plus 30 minutes, is 150 minutes total.
Why would I need to convert hours to minutes?
Plenty of tools only accept a single minutes value instead of separate hours and minutes fields: countdown timer apps, video and podcast editing software, and cinema listings that show a runtime like "135 min" instead of "2h 15m".
What's the difference between hours to minutes and hours to decimal?
Hours to minutes gives you a whole number of minutes, like 135, with nothing left over. Hours to decimal gives you a fraction of an hour instead, like 2.25, which is what payroll and invoicing systems expect. Use the hours to decimal calculator if you're logging billable time.
How many minutes is 3 hours 45 minutes?
3 hours 45 minutes is 225 minutes (3 × 60 = 180, plus 45, is 225).
Is 90 minutes the same as 1.5 hours?
Yes, 90 minutes and 1.5 hours describe the same duration, but they're two different formats. This calculator converts hours and minutes to a whole minutes total; use the hours to decimal calculator if you specifically need the 1.5 figure instead.
How many minutes is a 90 minute movie listed as 1h 30m?
That's already the answer: 90 minutes. A cinema listing showing 1h 30m and one showing 90 min describe the exact same runtime, just formatted differently.
What is 5 hours in minutes?
5 hours is 300 minutes (5 × 60 = 300), with no leftover minutes to add since there's no minutes component in the original duration.
What is 4 hours 20 minutes in minutes?
4 hours 20 minutes is 260 minutes (4 × 60 = 240, plus 20, is 260).
