The temperature conversion calculator featured on this page focuses on 3 of the main unit increments in measuring temperature: Celsius, Fahrenheit, and Kelvin. For all purpose temperature measurement, the two most common scales are Celsius and Fahrenheit.

Though formerly referred to as centigrade through 1948, the Celsius temperature scale was invented in the 1700s by Swedish astronomer Anders Celsius. The Celsius scale is widely adopted by most of the world as the standard in all purpose temperature measurement with the main exception being the United States. The United States currently mostly uses the Fahrenheit scale. The Fahrenheit scale was originally proposed in 1724 by the German physicist Daniel Gabriel Fahrenheit. In addition to the United States, there are a few additional countries which still rely on this temperature measurement including Palau, Belize, Burma, and Liberia.

In contrast, the Kelvin temperature scale is mainly an extension of the Celsius scale which is often primarily used for scientific calculations. With this scale, temperatures are not measured in terms of degrees but in terms of Kelvin.
