That reading is below absolute zero (-273.15°C / -459.67°F / 0 K) -
no physical temperature can be that low.
How to convert Rankine to Kelvin
K = °R ÷ 1.8
To convert Rankine to Kelvin, divide by 1.8 (equivalently, multiply by 5/9). Both scales are absolute, so zero maps to zero and the conversion is a pure ratio between Fahrenheit-sized and Celsius-sized degrees.
Worked examples
- Convert 540 °R: 540 ÷ 1.8 = 300 K
- Convert 671.67 °R: 671.67 ÷ 1.8 = 373.15 K (water boils)
