Degrees Celsius to degrees Rankine
Type a value in °C to get it in °R instantly.
That's about the temperature of boiling water. Water boils here at sea level.
What it means
How warm is that?
Reference temperatures are typical values at sea level. Water boils lower up a mountain, where the air pressure is less.
The math
How to convert °C to °R
Add 273.15, then multiply by 9/5: °R = (°C + 273.15) × 1.8. Rankine counts from absolute zero in Fahrenheit-sized degrees.
Example: 100 °C = 671.67 °R.

The units
About these units
Degrees Celsius (°C)
Celsius puts 0 at the melting point of ice and 100 at the boiling point of water at sea level. Almost every country uses it for weather and cooking.
Degrees Rankine (°R)
Rankine is to Fahrenheit what kelvin is to Celsius: it starts at absolute zero but uses Fahrenheit-sized degrees. US engineering thermodynamics still uses it.
