Unit Information

Kelvin (K)

Definition: The SI base unit of temperature, starting from absolute zero.

History: Named after British physicist Lord Kelvin.

Current Use: Used in science and engineering for precise measurements.

Celsius (°C)

Definition: A temperature scale where 0° is the freezing point of water and 100° is the boiling point.

History: Named after Swedish astronomer Anders Celsius.

Current Use: Used in most of the world for weather and science.

Fahrenheit (°F)

Definition: A temperature scale where 32° is the freezing point of water and 212° is the boiling point.

History: Developed by German physicist Daniel Gabriel Fahrenheit.

Current Use: Used primarily in the United States.

Rankine (°R)

Definition: An absolute temperature scale using Fahrenheit degrees.

History: Named after Scottish engineer William Rankine.

Current Use: Used in some engineering applications in the US.

Réaumur (°Ré)

Definition: A temperature scale where water freezes at 0° and boils at 80°.

History: Developed by René Antoine Ferchault de Réaumur.

Current Use: Historically used, now mostly obsolete.
