| 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. When it is zero degrees outside measured by the Fahrenheit system, it is very cold and you need a heavy coat to stay warm. When it is 100 degrees measured by the Fahrenheit system, it is very hot, and you probably want to jump in a swimming pool! |
