Key Stage 3
Meaning
Degrees Celsius are a scientific unit of temperature.
About Degrees Celsius
- Degrees Celsius is shortened to °C with the degree symbol ° followed by an upper case C.
- A degree Celsius is 100th of the temperature change between the ice melting and water boiling.
Key Stage 4
Meaning
Degrees Celsius are a scientific unit of temperature.
About Degrees Celsius
- Degrees Celsius is shortened to °C with the degree symbol ° followed by an upper case C.
- Degrees Celsius are 273° away from the SI unit for temperature; the Kelvin;
- 0°C = 273 Kelvin
- -273°C = 0 Kelvin (Absolute Zero the coldest temperature possible in the Universe).
- A change of 1°C is the same as change of 1 Kelvin.
- A degree Celsius is 100th of the temperature change between the melting point and Boiling Point|boiling point]] of water at normal atmospheric pressure.

Key Stage 5
Meaning
Degrees Celsius are a unit of temperature in the Celsius scale where 0°C is the temperature at which water freezes and 100°C is the temperature at which water boils at standard atmospheric pressure.
About the Celsius Scale
- Defined in terms of the triple point of water, where the temperature is exactly 0.01°C.
- Used worldwide for most temperature measurements except in scientific research where the Kelvin scale is preferred.
- Named after the Swedish astronomer Anders Celsius.
- Commonly used in everyday temperature measurements and weather reporting.
- The Celsius scale is part of the metric system.
- The interval between the freezing and boiling points of water is divided into 100 degrees.
- The Celsius scale is also used in various scientific and engineering contexts.
Examples
- Weather forecasts report temperatures in degrees Celsius.
- Laboratory measurements often use the Celsius scale for temperature readings.
