Unit History

Celsius

The degree Celsius is a unit of temperature on the Celsius scale, a temperature scale originally known as the centigrade scale. On the Celsius scale, the freezing and boiling points of water are 100 degrees apart. A temperature interval of 1 °F is equal to an interval of ​5⁄9 degrees Celsius.

Fahrenheit

The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit (1686–1736). On the Fahrenheit scale, the freezing point of water is 32°F and the boiling point is 212°F (at standard atmospheric pressure). This puts the boiling and freezing points of water 180 degrees apart.Therefore, a degree on the Fahrenheit scale is ​1⁄180 of the interval between the freezing point and the boiling point.

Kelvin

The kelvin is the base unit of temperature in the International System of Units (SI), having the unit symbol K. It is named after the Belfast-born Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907).
