The Celsius scale is the most commonly used temperature scale and the standard used for most applications by the scientific community worldwide. The boiling point of water is 100 °C. The freezing point is 0 °C. The word centigrade is used in many languages to describe Celsius.
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".
