About these units
Rankine (°R)
- Definition
- The degree Rankine (°R) is an absolute temperature scale that uses Fahrenheit-sized degrees starting at absolute zero.
- History
- Proposed by Scottish engineer William Rankine in 1859 as the absolute counterpart to Fahrenheit.
- Current use
- Rankine appears in some US engineering and thermodynamics work, particularly in aerospace.
Fahrenheit (°F)
- Definition
- The degree Fahrenheit (°F) is a temperature unit where water freezes at 32° and boils at 212° at standard pressure.
- History
- Introduced by physicist Daniel Gabriel Fahrenheit in 1724 using brine and body temperature as reference points.
- Current use
- Fahrenheit remains the common temperature scale in the United States and a few other territories.
