--- title: Converting Units Minutes to Hours --- ## Converting Units Minutes to Hours A minute is defined as one sixtieth of an hour. Conversion between minutes and hours is thus given by
th = tmin / 60
tmin = th * 60
where tmin is the time in minutes and th is the time in hours.
The symbols for time in minutes and hours are **min** and **h** respectively (The International System of Units, 8th edition, [Chapter 4: Units outside the SI](https://www.bipm.org/utils/common/pdf/si_brochure_8_en.pdf)).
### Examples
Converting from time in minutes to time in hours:
```
90 minutes = (90 / 60) hours = 1.5 hours
```
Converting from time in hours to time in minutes:
```
24 hours = (24 * 60) minutes = 1440 minutes
```
