What is Rankine to Fahrenheit Conversion?
Converting Rankine to Fahrenheit is one of the simplest temperature conversions—just subtract 459.67. Both scales use identical degree sizes; they only differ in where zero is defined.
The Simple Formula
The formula couldn't be easier: °F = °R − 459.67. This works because:
- Rankine and Fahrenheit degrees are exactly the same size
- 0°R equals -459.67°F (absolute zero)
- Subtracting 459.67 shifts back to the Fahrenheit reference point
Common Temperature Examples
- 460°R ≈ 0°F
- 492°R ≈ 32°F (freezing point)
- 530°R ≈ 70°F (room temperature)
- 672°R ≈ 212°F (boiling point)
When to Use This Converter
If you encounter Rankine temperatures in textbooks, technical documents, or engineering problems, this converter quickly translates them to familiar Fahrenheit readings.

Common Temperature Conversions
- 420°R = -39.67°F - Very cold
- 460°R = 0.33°F - Around zero Fahrenheit
- 492°R = 32.33°F - Around freezing
- 530°R = 70.33°F - Room temperature
- 560°R = 100.33°F - Hot day
- 672°R = 212.33°F - Around boiling
Mental Math
For quick estimates, subtract 460 from Rankine. So 530°R ≈ 70°F (exact: 70.33°F). Close enough for everyday use!
Understanding Low Values
Rankine values below 460 convert to negative Fahrenheit. For example, 400°R = -59.67°F.

Frequently Asked Questions
What is the formula to convert Rankine to Fahrenheit?
Simply subtract 459.67: °F = °R − 459.67. This is the inverse of Fahrenheit to Rankine conversion.
Can I just subtract 460 for a quick estimate?
Yes, subtracting 460 gives a close approximation. The exact offset is 459.67, so your estimate will be within 0.33°F.
Is 500°R hot or cold?
500°R = 40.33°F, which is cool—just above freezing. Remember: 492°R ≈ 32°F (freezing point).
Can the result be negative?
Yes. Rankine values below 459.67 convert to negative Fahrenheit. For example, 400°R = -59.67°F.
What is room temperature in Rankine?
Comfortable room temperature of about 70°F equals 529.67°R, approximately 530°R.
Are Rankine and Fahrenheit degrees the same size?
Yes, exactly. A 1-degree change in Rankine equals a 1-degree change in Fahrenheit. The only difference is where zero is defined.
