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:

1. Identify the conversion factor for hr to min using the known equality: 1 hr = 60 min
2. Multiply the number of hours by 60 to get total minutes

Example problem: Convert 3 hours to minutes

1. Use 60 as the conversion factor: 1 hr = 60 min
2. 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

1. Use 60 as the conversion factor: 1 hr = 60 min
2. Multiply 0.42 hours by 60 minutes per hour
   0.42 × 60 = 25.2 minutes

Example problem: Convert 0.75 hours to minutes

1. Use 60 as the conversion factor: 1 hr = 60 min
2. 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

Formula

Mathematically, converting hours to minutes you'd write the equation including the units. Using the example coverting 3 hours to minutes the equation is:

3 hours × 60 minutes per 1 hour = 3 hr × 60 min/hr

You can cancel out the hours units and you are left with only minutes

3 hr × 60 min/hr = 180 min

The formula to convert hours to minutes is

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

Hour

An hour is a unit of time. The symbol for hour is h and is often abbreviated hr in everyday usage. Equating hours to other units of time, 1 hour = 60 minutes = 3600 seconds = 1/24 day = 0.0416 days.

Minute

A minute is a unit of time. The symbol for minutes, and its abbreviation, are both min. Equating minutes to other units of time, 1 minute = 60 seconds = 1/60 hour = 0.016 hours = 1/1440 day = 0.000694 days.

Hours to Minutes Charts of Common Conversions

Charts are printable by using the Print Chart link at the bottom of each chart.

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.
