| Fahrenheit |
When we use the word Fahrenheit, we are talking about a system people can use when they measure temperature. In America, people use the Fahrenheit system, but, in most other countries, they use a system called Celsius. When you see the letter F after a temperature, as in 72° F, the F stands for Fahrenheit.
