Converting Celsius to Rankine
Converting Celsius to Rankine is primarily used in engineering thermodynamics in the United States, connecting the metric temperature scale to an absolute temperature scale based on Fahrenheit degrees.
Mathematical Relationship
The formula to convert Celsius to Rankine is: °R = (°C + 273.15) × 9/5. This involves first converting to Kelvin and then scaling by the Fahrenheit factor.

Unit Definitions
Celsius
The Celsius scale (symbol: °C) is a temperature scale used by the International System of Units (SI). It defines 0°C as the freezing point of water and 100°C as the boiling point of water at standard atmospheric pressure.
Rankine
The Rankine scale (symbol: °R) is an absolute temperature scale named after Scottish engineer William John Macquorn Rankine, who proposed it in 1859. The zero point of the Rankine scale is absolute zero, and a one-degree change in Rankine is equal to a one-degree change in Fahrenheit.
Historical Context
The Rankine scale was proposed in 1859, after both the Celsius (1742) and Kelvin (1848) scales. It was created to provide an absolute temperature scale that was compatible with the Fahrenheit scale, similar to how Kelvin relates to Celsius.
