Frequently asked questions
Symbols and assumptions
- °F
- Input unit — degree Fahrenheit
- °R
- Output unit — degree Rankine
- K
- Base unit used internally for temperature
- • Both units measure temperature, so the physical quantity is unchanged by the conversion.
- • The two units are related by a defined equation rather than a single multiplier, so that equation is applied directly.
- • Values are converted through the SI base unit for this quantity rather than pair by pair.
