How to Convert Hours to Minutes

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
Multiply hours by the conversion ratio and cancel units to convert the value to min
- 5 hr × 60 min / 1 hr = (5 × 60) min = 300 min

For quick conversions multiply by 60
min × 60 = hr

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

\[ \text{total minutes} = \text{total hours} \times 60 \dfrac{\text{minutes}}{\text{hour}} \]

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
