Celsius to Rankine

Convert degrees Celsius to degrees Rankine with this simple formula:

degrees Rankine = ( [°C] + 273.15 ) × 9 / 5

Insert the [°C] temperature measurement in the formula and then solve to find the result.

For example, let's convert 50 °C to degrees Rankine:

50 °C = ( ( 50 + 273.15 ) × 9 / 5 ) = 581.67 °R

The Celsius scale and the Rankine scale are both used to measure temperature. Read on to learn more about each of them.


The Celsius temperature scale, also commonly referred to as the centigrade scale, is defined in relation to the kelvin. Specifically, degrees Celsius is equal to kelvins minus 273.15.[1]

The degree Celsius is the SI derived unit for temperature in the metric system. A degree Celsius is sometimes also referred to as a degree centigrade. Celsius can be abbreviated as C; for example, 1 degree Celsius can be written as 1 °C.

Important Temperatures In Degrees Celsius

Temperature Degrees Celsius
Absolute Zero -273.15 °C
Freezing Point of Water 0 °C
Triple Point of Water 0.01 °C
Boiling Point of Water 100 °C


The Rankine scale is an absolute temperature scale that uses absolute zero as the starting point, much like the Kelvin scale. The key difference between the Rankine scale and the Kelvin scale is that an increment of one degree rankine is equal to an increment of one degree Fahrenheit, not Celsius as in the Kelvin scale. The base of the Rankine scale starts at absolute zero, thus 0 degrees rankine are equal to −459.67 degrees Fahrenheit.

Rankine can be abbreviated as R, and are also sometimes abbreviated as Ra. For example, 1 degree Rankine can be written as 1 °R or 1 Ra.
