That reading is below absolute zero (-273.15°C / -459.67°F / 0 K) -
no physical temperature can be that low.
How to convert Fahrenheit to Rankine
°R = °F + 459.67
Fahrenheit to Rankine is the simplest conversion on this site: add 459.67. Rankine is simply Fahrenheit re-zeroed at absolute zero, the way Kelvin re-zeroes Celsius - degree sizes are identical between °F and °R, so no multiplication is needed.
Worked examples
- Convert 72°F: 72 + 459.67 = 531.67 °R (room temperature)
- Convert 32°F: 32 + 459.67 = 491.67 °R (water freezes)
- Convert -459.67°F: -459.67 + 459.67 = 0 °R (absolute zero)

Frequently asked questions
Why does Rankine exist when Kelvin already does?
Same reason Fahrenheit coexists with Celsius: US engineering practice. Rankine gives absolute temperatures in Fahrenheit-sized degrees, so US thermodynamic tables and gas-law work stay in familiar units.
