How many degrees Rankine are in 1 degree Fahrenheit?

1 degree Fahrenheit equals 460.67 °R.

How do I convert degrees Rankine back to degrees Fahrenheit?

Use the reverse converter: 1 degree Rankine equals -458.67 °F.

Yes. It uses the exact SI/NIST definitions of each unit and shows up to 6 significant digits.

To convert degrees Fahrenheit to degrees Rankine, use the formula °R = °F + 459.67.

°R = °F + 459.67

20 °F → °R = °F + 459.67 → 479.67 °R

Kelvin and Rankine start at absolute zero, so negative values are physically impossible.

Degree Fahrenheit (°F): Used for everyday temperatures in the US and a few other countries. Proposed by Daniel Fahrenheit in 1724; water freezes at 32 °F and boils at 212 °F.
Degree Rankine (°R): An absolute scale using Fahrenheit-sized degrees, zero at absolute zero. Used in some US thermodynamics and engineering work.
