More About fahrenheit
Fahrenheit made his scale in 1724. He wanted a way to show temps. He used ice and salt to find the cold point. He also used the heat of a body to find the warm point.
We use Fahrenheit to check the weather. It helps us dress right for the day. We can plan trips based on the temp too.
Fahrenheit is still used today. Some places use Celsius too. Both ways help us know how to stay safe and warm!
