Rankine (R) and Celsius (°C) are two different temperature scales commonly used to measure temperature.
Rankine is an absolute temperature scale commonly used in engineering and thermodynamics. It is based on the Fahrenheit scale but starts from absolute zero. In the Rankine scale, absolute zero is 0 R, and the size of one degree Rankine is equal to the size of one degree Fahrenheit. Therefore, the Rankine scale has the same increments as the Fahrenheit scale but starts from absolute zero.
Celsius, also known as Centigrade, is a temperature scale widely used in most of the world. It is based on the Celsius degree, which is defined as 1/100th of the temperature difference between the freezing point (0°C) and boiling point (100°C) of pure water at sea level atmospheric pressure. In the Celsius scale, the freezing point of water is 0°C, and the boiling point of water is 100°C at sea level.
The Rankine and Celsius scales are two different temperature scales. To convert from Rankine (R) to Celsius (°C), you can use the following formula:
°C = (R – 491.67) × 5/9
In this formula, you subtract 491.67 from the temperature in Rankine and then multiply the result by 5/9 to obtain the temperature in Celsius.

Formula Celsius to Rankine: To convert from Celsius (°C) to Rankine (R), you can use the following formula: R = (°C + 273.15) × 9/5 + 491.67
The Rankine (R) scale is based on the Fahrenheit scale, so the formula to convert from Fahrenheit (°F) to Rankine is: R = °F + 459.67
The unit of Rankine is denoted by R.
To convert 32 degrees Fahrenheit (°F) to Rankine (R), you can use the formula mentioned above: R = °F + 459.67 R = 32 + 459.67 R = 491.67
32 degrees Fahrenheit (°F) is equal to 0 degrees Celsius (°C). The two temperature scales have different reference points, so the numerical values differ, but they intersect at -40 degrees, and at -40 degrees, 32°F is equal to 0°C.
The symbol for Rankine is R.
