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 Celcius 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.
