Since there are 60 minutes in an hour, minutes equals hours times 60 minutes per hour or, minutes = hours × 60 minutes/hour.
Example: 5 hours to minutes conversion.
- Identify the unit conversion ratio for hr to min
- Use the known equality:
1 hr = 60 min - Divide both sides by minutes to find the conversion ratio,
60 min / 1 hr = 1
- Use the known equality:
- Multiply hours by the conversion ratio and cancel units to convert the value to min
- 5
hr× 60 min / 1hr= (5 × 60) min = 300 min
- 5
For quick conversions multiply by 60
min × 60 = hr

Formula
Mathematically, converting say 3 hours to minutes, we write our equation with units that will convert to minutes.
3 hours × 60 minutes per 1 hour = 3 hr × 60 min/hr
Cancel out the hours and we are left with minutes
3 hr × 60 min/hr = 180 min
\[ \text{total minutes} = \text{total hours} \times 60 \dfrac{\text{minutes}}{\text{hour}} \]
Hour
An hour is a unit of time. The symbol for hour is h and is often abbreviated hr in everyday usage. Relating hours to other units of time 1 hour = 60 minutes = 3600 seconds = 1/24 day = 0.0416 days.

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
