Unit definitions
What is a degree Rankine?
The degree Rankine is an absolute temperature scale whose zero is absolute zero but whose degree size matches Fahrenheit. It is used in some United States engineering fields, especially thermodynamics and combustion. Water freezes at about 491.67 °R.
What is a degree Fahrenheit?
The degree Fahrenheit is the customary temperature unit in the United States, with water freezing at 32 °F and boiling at 212 °F. Each Fahrenheit degree is 5/9 of a kelvin, so the scale is finer than Celsius. Normal human body temperature is about 98.6 °F.
