How to Convert Fahrenheit to Rankine
To Celsius: °C = (°F − 32) × 5/9. To Kelvin: K = (°F − 32) × 5/9 + 273.15. To Rankine: °R = °F + 459.67.
The Fahrenheit scale has 180 degrees between freezing (32 °F) and boiling (212 °F), compared to 100 degrees in Celsius.
For example, 1 Fahrenheit (°F) = 460.67 Rankine (°R).

About Fahrenheit (°F)
Definition
The degree Fahrenheit is a temperature unit where water freezes at 32 °F and boils at 212 °F at standard atmospheric pressure, with 180 equal divisions between these points.
Mathematical Relationship
The Fahrenheit scale has 180 degrees between freezing (32 °F) and boiling (212 °F), compared to 100 degrees in Celsius.
Conversion Formula
To Celsius: °C = (°F − 32) × 5/9. To Kelvin: K = (°F − 32) × 5/9 + 273.15. To Rankine: °R = °F + 459.67.
Practical Applications
US weather forecasts, oven temperatures in American cooking, pool and hot tub settings, and thermostat controls in American homes.
Interesting Facts
Fahrenheit originally set human body temperature as 96 °F (a number divisible by 12). The modern accepted value is 98.6 °F (37 °C).
Common Mistakes
Forgetting to subtract 32 before multiplying by 5/9 when converting to Celsius. Also confusing °F with °C in international recipes.
Educational Tips
Quick anchors: 32 °F = freezing, 72 °F = comfortable room, 98.6 °F = body, 212 °F = boiling. For quick °F→°C: subtract 30, divide by 2.
About Rankine (°R)
Definition
The degree Rankine is an absolute temperature scale using the Fahrenheit degree size, where 0 °R equals absolute zero (−459.67 °F).
Mathematical Relationship
°R = °F + 459.67. The Rankine scale is to Fahrenheit what Kelvin is to Celsius. Same degree size as Fahrenheit.
Conversion Formula
To Fahrenheit: °F = °R − 459.67. To Celsius: °C = (°R − 491.67) × 5/9. To Kelvin: K = °R × 5/9.
Practical Applications
US engineering thermodynamics calculations, gas turbine design, and some aerospace engineering applications.
Interesting Facts
Water freezes at 491.67 °R and boils at 671.67 °R. The Rankine scale is one of the four main temperature scales still in use.
Common Mistakes
Confusing Rankine with Réaumur — both use 'R' but are completely different scales. Use °R vs. °Ré to distinguish.
Educational Tips
Rankine is to Fahrenheit as Kelvin is to Celsius. Both absolute scales start at 0 = absolute zero, just with different degree sizes.
