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!
Everyone in the world measures temperature in degrees, but the amount of temperature between one degree and the next degree in the Fahrenheit system is smaller than the amount of temperature between degrees in the Celsius system. That's why 72 degrees Fahrenheit feels like a nice temperature to be outside, but 72 degrees Celsius is too hot for people to stay alive! Another big difference between the two systems is that water becomes ice when the temperature is 32 degrees Fahrenheit, but water becomes ice at 0 degrees Celsius.
