How many degrees Rankine are in 1 degree Celsius?

1 degree Celsius equals 493.47 °R.

How do I convert degrees Rankine back to degrees Celsius?

Use the reverse converter: 1 degree Rankine equals -272.594 °C.

Yes. It uses the exact SI/NIST definitions of each unit and shows up to 6 significant digits.

To convert degrees Celsius to degrees Rankine, use the formula °R = (°C + 273.15) × 9/5.

°R = (°C + 273.15) × 9/5

90 °C → °R = (°C + 273.15) × 9/5 → 653.67 °R

Kelvin and Rankine start at absolute zero, so negative values are physically impossible.

Degree Celsius (°C): The temperature scale used by most countries and in science. Defined by Anders Celsius in 1742; 0 °C is water's freezing point and 100 °C its boiling point at sea level.
Degree Rankine (°R): An absolute scale using Fahrenheit-sized degrees, zero at absolute zero. Used in some US thermodynamics and engineering work.
