Still image from Shedding Light on Heat: The Kelvin Scale (Episode 4)

The Celsius and Fahrenheit scales were both built around water, either the freezing point, the boiling point, or some combination of water and a chemical. The Kelvin temperature scale is used by scientists because they wanted a temperature scale where zero reflects the complete absence of thermal energy. Part of the "Shedding Light on Heat" series.
