About these units
Kelvin
The Kelvin scale was proposed by physicist William Thomson (Lord Kelvin) in 1848. Zero Kelvin represents absolute zero — the point at which molecular motion theoretically stops. It has been the SI base unit of thermodynamic temperature since 1954.
Celsius
The Celsius scale has been used since the mid-18th century and is the everyday temperature standard in most countries. Its anchor points (0°C freezing, 100°C boiling of water) make it intuitive for weather and cooking.
Frequently asked questions
300 - 273.15 = 26.85°C — approximately room temperature.
373.15 - 273.15 = 100°C — the boiling point of water at sea level.
77 - 273.15 = -196.15°C — the temperature of liquid nitrogen.
