Frequently Asked Questions
What is the formula?
The formula is °F = °R − 459.67. Just subtract 459.67 — both scales share the same degree size.
Can I subtract 460 for a quick estimate?
Yes. Subtracting 460 stays within 0.33°F of the exact value.
Is 500°R hot or cold?
500°R = 40.33°F, which is cool — just above freezing (492°R ≈ 32°F).
Can the result be negative?
Yes. Rankine values below 459.67 convert to negative Fahrenheit. For example, 400°R = -59.67°F.
