Degrees CelsiusTemperature is a measure of heat.

Temperature tells us how hot or cold something is.

Thermometers are used to measure temperature.

We usually measure temperature in degrees Celsius (˚C) but some parts of the world use degrees Fahrenheit (˚F).

The Celsius scale is based on the freezing point of water being 0 degrees and the boiling point being 100 degrees.
