°F

Rankine

671.67

°R

212 °F = 671.67 °R

°R = °F + 459.67

Fahrenheit to Rankine: To convert fahrenheit to rankine, apply °R = °F + 459.67. Unlike linear unit conversions, fahrenheit and rankine use different zero points, so a fixed multiplier is not sufficient.

How to Convert Fahrenheit to Rankine

Converting between fahrenheit and rankine requires both a scale factor and an offset because the two scales use different zero points. The formula below handles both adjustments.

Conversion Formula

  • Fahrenheit to Rankine: °R = °F + 459.67
  • Rankine to Fahrenheit: °F = °R − 459.67

Understanding the Units

What is a Fahrenheit?

The degree Fahrenheit is a temperature scale on which water freezes at 32 °F and boils at 212 °F at standard atmospheric pressure.

Named after Daniel Gabriel Fahrenheit (1686–1736), German-Polish physicist who developed the mercury thermometer.

Common contexts: US weather, US cooking.

FAQ

How do you convert Fahrenheit to Rankine?

Add 459.67 to the Fahrenheit value. For example, 72 °F + 459.67 = 531.67 °R.

What is body temperature (98.6 °F) in Rankine?

98.6 °F equals 558.27 °R.

Who created the Rankine scale?

The Rankine scale was proposed by Scottish physicist William John Macquorn Rankine in 1859 as an absolute temperature scale using Fahrenheit-sized degrees.

Can Fahrenheit values produce a Rankine below zero?

Physically no, because temperatures below absolute zero (-459.67 °F) do not occur in classical thermodynamics. Mathematically, any °F below -459.67 would give a negative °R.

How do you convert rankine back to fahrenheit?

Use the inverse formula: °F = °R − 459.67.

Why isn't fahrenheit-to-rankine a simple multiplication?

Fahrenheit and Rankine use different zero points, so the relationship includes both a scale factor and an offset. The scale factor alone gives the rate of change but not the absolute value.
