Convert Celsius to degrees in Rankine.

## Celsius °C to Rankine °R Formula

°R equals °C multiplied by, 9/5, plus 491.67.

Since 9/5 equals 1.8, another way to write this formula, which can be easier to remember for some people is as follows. This formula is stated: °R equals °C multiplied 1.8 plus 491.67.

## How to Convert Celsius to Rankine

- Multiply degrees Celsius by 1.8 (or 9/5)
- Add 491.67 to the product from step 1

For example, to convert 15 degrees Celsius (centigrade) to degrees Rankine, we plug our numbers into the formula as shown below:

°R = (15 × (9/5)) + 491.67

°R = (15 × 1.8) + 491.67

°R = 27 + 491.67

°R = 518.67

15 degrees Celsius is equal to 518.67 degrees Rankine.

This calculator will show the steps to solve the °C to °R formula so you know how make the conversion yourself.

## Rankine

Rankine is a temperature scale and degrees Rankine are units of temperature on that scale. The symbol for degree Rankine is °R. A temperature such as 500 °R is stated "five-hundred degrees Rankine". On the Rankine scale the boiling point of water is 671.67 °R, the freezing point of water is 491.67 °R and absolute zero is 0 °R. The Rankine scale does not contain negative values.

## Celsius

Celsius is a temperature scale and degrees Celsius are units of temperature on that scale. The symbol for degree Celsius is °C. A temperature such as 15 °C is stated "fifteen degrees Celsius". On the Celsius scale the boiling point of water is 100 °C, the freezing point of water is 0 °C and absolute zero is −273.15 °C.
