Convert Hours to Minutes
As with any conversion, first find the conversion factor to convert between units of measure. A conversion factor is a multiplier (or divider) used to convert a quantity from one unit of measure to another.
Since there are 60 minutes in an hour, minutes equals hours times 60. You can also think of it as
minutes = hours × 60 minutes/hour
The steps:
- Identify the conversion factor for hr to min using the known equality: 1 hr = 60 min
- Multiply the number of hours by 60 to get total minutes
Example problem: Convert 3 hours to minutes
- Use 60 as the conversion factor: 1 hr = 60 min
- Multiply 3 hours by 60 minutes per hour
3 × 60 = 180 minutes
Sometimes you'll see hours written as a decimal. Knowing the conversion factor makes it easy to convert decimal hours to minutes.
Example problem: Convert 0.42 hours to minutes
- Use 60 as the conversion factor: 1 hr = 60 min
- Multiply 0.42 hours by 60 minutes per hour
0.42 × 60 = 25.2 minutes
Example problem: Convert 0.75 hours to minutes
- Use 60 as the conversion factor: 1 hr = 60 min
- Multiply 0.75 hours by 60 minutes per hour
0.75 × 60 = 45 minutes
Just remember, for quick conversions from hours to minutes, multiply hours by 60
hours × 60 = minutes

Example:
Convert 7.25 hours to minutes.
7.25 hr × 60 min/hr
= 7.25 hr × 60 min/hr
= 435 min
Convert 435 minutes to seconds.
435 min × 60 sec/min
= 435 min × 60 sec/min
= 26,100 sec
Convert 7.25 hours to hh:mm:ss format.
We have 7 hours with 0.25 decimal hours.
From the table above we see 0.25 hours = 15 minutes
Alternatively, 0.25 hours × 60 minutes/hour = 15 minutes.
Therefore, 7.25 hours = 07:15:00
