Understanding temperature scales

Celsius (°C)

Used by most of the world. Water freezes at 0°C and boils at 100°C.

Fahrenheit (°F)

Used primarily in the United States. Water freezes at 32°F and boils at 212°F.

Kelvin (K)

The base unit of temperature in the International System of Units (SI). 0 K is absolute zero.

Rankine (°R)

An absolute scale used in engineering systems that employ Fahrenheit. 0°R is absolute zero.

Réaumur (°Re)

A temperature scale where water freezes at 0°Re and boils at 80°Re. Once widely used in Europe, it is now mostly of historical interest.
