Degrees Rankine to Degrees Fahrenheit
1 °R ≈ -458.7 °F. Edit either value to convert instantly.
Conversion formula
°F = ((°R × (5 / 9)) + (0) × (1.8)) − (459.67)1 °R = -458.67 °F
degree Rankine (°R)
Rankine is an absolute temperature scale with 1 °R = 5/9 K; 0 °R is absolute zero.

degree Fahrenheit (°F)
Fahrenheit uses °C = (°F − 32) × 5/9; 32 °F = 0 °C and 212 °F = 100 °C.

Frequently asked questions
How many degrees Fahrenheit are in 1 degree Rankine?
1 °R ≈ -458.7 °F. °F = ((°R × (5 / 9)) + (0) × (1.8)) − (459.67)
How do I convert °R to °F?
°F = ((°R × (5 / 9)) + (0) × (1.8)) − (459.67)
Why does this conversion need more than multiplication?
Temperature scales have different zero points. Apply the scale and offset in the formula; below absolute zero is a mathematical result only.
