|There are two main temperature scales:
°F, the Fahrenheit Scale (used in the US), and
°C, the Celsius Scale (part of the Metric System, used in most other countries)
They both measure temperature, just using different numbers.
* If you freeze water, it measures 0° in Celsius, but 32° in Fahrenheit.
* If you boil water, it measures 100° in Celsius, but 212° in Fahrenheit.
* The difference between freezing and boiling is 100° in Celsius, but 180° in Fahrenheit.
