How to convert Rankine to Celsius
To convert Rankine to Celsius, subtract 491.67 then multiply by 5/9. Formula: °C = (°R − 491.67) × 5/9. For example, 671.67°R = (671.67 − 491.67) × 5/9 = 100°C.
Going the other way — to convert Celsius to Rankine — multiply by 9/5 then add 491.67. So 100°C × 9/5 + 491.67 = 671.67°R.
0°R = absolute zero = −273.15°C. Rankine uses Fahrenheit-sized degrees while Celsius uses metric degrees. To convert between them you need to account for both the different zero points and different degree sizes.
