Temperature measures how hot or cold something is. You measure that with a thermometer. As the mercury inside rises, that means it's getting hotter. When the mercury drops, that means it's getting colder.

Temperature can be measured in Fahrenheit, Celsius, or Kelvin. What’s the difference?

Here in the United States we mainly use Fahrenheit. While other parts of the world, who use the metric system, use Celsius. Scientists generally use Kelvin.

You can use math to switch between Fahrenheit and Celsius. You may need an adult to help.

Celsius = (F - 32) / 1.8

Fahrenheit = C x 1.8 + 32
