Fahrenheit to Rankine Converter
Convert degrees Fahrenheit (°F) to degrees Rankine (°R) instantly. Type a value — the result updates as you type, and the swap button converts the other way.
Fahrenheit to Rankine formula
°R = °F + 459.67
To convert degrees Fahrenheit to degrees Rankine, apply the formula °R = °F + 459.67. For example, 70 °F:
°R = 70 + 459.67°R = 529.67
So 70 °F = 529.67 °R.
Mental math shortcut
This conversion is exact, so there is no need to estimate: it uses a fixed offset or the exact 9/5 factor.

About the units
Fahrenheit (°F)
The Fahrenheit scale puts water’s freezing point at 32 °F and boiling point at 212 °F. It is the everyday temperature scale in the United States.
Rankine (°R)
The Rankine scale starts at absolute zero like Kelvin but uses Fahrenheit-sized degrees (0 °R = −459.67 °F). It is still used in some US engineering work.
