Convert a duration from hours to minutes. The converter works with whole numbers and decimal hours, making it useful for schedules, timesheets, journeys, and everyday time calculations.
Hours to Minutes Formula
One hour contains exactly 60 minutes:
1 h = 60 min
To convert hours to minutes, multiply the number of hours by 60:
Minutes = hours × 60
Written as a unit conversion:
Hours × (60 minutes ÷ 1 hour) = minutes
Example: Convert 2.5 hours to minutes
Multiply 2.5 by 60:
2.5 h × 60 min/h = 150 min
Therefore, 2.5 hours equals 150 minutes.
Converting Hours and Minutes Together
If a duration contains both hours and minutes, convert the hours first and then add the remaining minutes.
Example: Convert 3 hours and 20 minutes
First, change the three hours into minutes:
3 × 60 = 180 minutes
Then add the extra 20 minutes:
180 + 20 = 200 minutes
Therefore, 3 hours and 20 minutes equals 200 minutes.
Hours to Minutes Conversion Table
| Hours (h) | Minutes (min) |
|---|---|
| 0.1 h | 6 min |
| 0.25 h | 15 min |
| 0.5 h | 30 min |
| 0.75 h | 45 min |
| 1 h | 60 min |
| 1.5 h | 90 min |
| 2 h | 120 min |
| 2.5 h | 150 min |
| 3 h | 180 min |
| 4 h | 240 min |
| 5 h | 300 min |
| 8 h | 480 min |
| 10 h | 600 min |
| 12 h | 720 min |
| 24 h | 1,440 min |
| 40 h | 2,400 min |
| 48 h | 2,880 min |
| 72 h | 4,320 min |
Understanding Decimal Hours
A decimal hour represents a fraction of 60 minutes. The digits after the decimal point should not be read as ordinary clock minutes.
- 0.25 hours = 15 minutes
- 0.5 hours = 30 minutes
- 0.75 hours = 45 minutes
For example, 2.30 hours does not mean 2 hours and 30 minutes. The decimal part must be multiplied by 60:
0.30 × 60 = 18 minutes
Therefore, 2.30 hours equals 2 hours and 18 minutes, or 138 minutes altogether.
When Is This Conversion Useful?
Converting hours to minutes can help with lesson plans, appointment schedules, cooking times, exercise sessions, travel estimates, timesheets, project planning, and equipment run times.
Minutes are often easier to use when adding several short periods together or comparing durations that are less than a few hours.
