Kelvin is the unit of measure for temperature adopted by the International System of Units. Absolute zero is 0 K, equivalent to -273.15 °C. Kelvin uses the same interval as Celsius. The Kelvin scale is named after Baron Kelvin of Largs, who described the need for an absolute thermometric scale in his paper "On an Absolute Thermometric Scale".
Widely used in the United States, the Fahrenheit scale is named after Daniel Gabriel Fahrenheit, inventor of the alcohol and mercury thermometers. The freezing point of water is 32 °F, and the boiling point is 212 °F.
