Degrees Fahrenheit to degrees Rankine
Type a value in °F to get it in °R instantly.
559.7°R
That's between body temperature and a hot bath. Hot: above human body temperature.
What it means
How warm is that?
Reference temperatures are typical values at sea level. Water boils lower up a mountain, where the air pressure is less.
The math
How to convert °F to °R
Add 459.67: °R = °F + 459.67. Rankine and Fahrenheit share the same degree size.
Example: 100 °F = 559.67 °R.

About these units
Degrees Fahrenheit (°F)
Fahrenheit puts water freezing at 32° and boiling at 212°, so each degree is smaller than a Celsius degree. The US, its territories and a few islands still use it.
Degrees Rankine (°R)
Rankine is to Fahrenheit what kelvin is to Celsius: it starts at absolute zero but uses Fahrenheit-sized degrees. US engineering thermodynamics still uses it.
