How many degrees Fahrenheit are in 1 degree Rankine?

1 degree Rankine equals -458.67 °F.

How do I convert degrees Fahrenheit back to degrees Rankine?

Use the reverse converter: 1 degree Fahrenheit equals 460.67 °R.

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

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

°F = °R − 459.67

50 °R → °F = °R − 459.67 → -409.67 °F

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

Degree Rankine (°R): An absolute scale using Fahrenheit-sized degrees, zero at absolute zero. Used in some US thermodynamics and engineering work.
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.
