Unit Definitions
Fahrenheit (°F)
Imperial scale with 32°F at freezing and 212°F at boiling.
Add 459.67 to convert to Rankine. Subtract 32 and multiply by 5/9 to convert to Celsius; subtract 32, multiply by 5/9, and add 273.15 to reach Kelvin.
Rankine (°R)
Absolute temperature scale using Fahrenheit-sized degrees, starting at absolute zero.
Rankine to Fahrenheit subtracts 459.67. Rankine to Kelvin multiplies by 5/9. Rankine to Celsius subtracts 491.67 then multiplies by 5/9.
Common Use Cases
- US thermodynamics (Rankine scale).
- Gas law problems in °R.
- Engineering textbooks.
- Converting °F to absolute scale.
Understanding the Conversion
°R = °F + 459.67. Only an offset—same degree size.
0°F = 459.67°R · 32°F = 491.67°R · −459.67°F = 0°R.
Rankine is Fahrenheit shifted to absolute zero—no multiply step unlike °C↔°F.
US thermodynamics (Rankine scale). The table and FAQ on this page walk through the factor if you need it.
