## 将单位分钟转换为小时
一分钟定义为六十分之一小时。因此,分钟和小时之间的转换由
```
t<sub>h</sub> = t<sub>min</sub> / 60
t<sub>min</sub> = t<sub>h</sub> * 60
```
其中t min是以分钟为单位的时间t h是以小时为单位的时间。
分钟和小时的时间符号分别为**min**和**h** 国际单位制第8版 [第4章SI以外的单位](https://www.bipm.org/utils/common/pdf/si_brochure_8_en.pdf) )。
### 例子
从分钟转换为以小时为单位的时间:
```
90 minutes = (90 / 60) hours = 1.5 hours
```
以小时为单位转换为以分钟为单位的时间:
```
24 hours = (24 * 60) minutes = 1440 minutes
```
