Celsius to Rankine Converter

Convert Celsius to Rankine instantly using the correct formula: multiply by 1.8 and add 491.67. The Rankine scale is an absolute temperature scale like Kelvin, but it uses the size of a Fahrenheit degree instead of a Celsius one, and it is common in some US engineering and thermodynamics work. Because Rankine has its zero at absolute zero rather than at the freezing point of water, you cannot just scale by a single number, which is why the offset of 491.67 is needed. This tool applies the full formula, so a value like 0 degrees Celsius correctly becomes 491.67 Rankine. Type any Celsius value, including negatives, and the Rankine result appears live as you type.
