## Celsius to Rankine (℃ to ºR) conversion formula

**Rankine** = (**Celsius** * 1.8) + 491.67

## Converting from Celsius to Rankine

Converting from Celsius to Rankine allows us to compare temperatures in two different scales. The Celsius scale is commonly used in most parts of the world, while the Rankine scale is primarily used in scientific and engineering applications. The Rankine scale is an absolute temperature scale based on the Fahrenheit scale, meaning it starts at absolute zero, where all molecular motion ceases.

To convert from Celsius to Rankine, we need to convert the Celsius temperature to Fahrenheit by multiplying by 1.8 and adding 32. Next add the absolute zero offset of 459.67.

For example, if we have a temperature of 25°C, we would multiply this by 1.8 and add 32 giving 77°F. Now add 459.67 to this value to obtain 536.67°R.

Converting temperatures between Celsius and Rankine is particularly useful in scientific and engineering fields where absolute temperature measurements are required. It allows for accurate comparisons and calculations involving temperature changes, energy transfer, and thermodynamic processes. Understanding how to convert between these two scales expands our ability to work with temperature data and ensures consistency in scientific analysis and experimentation.

## About Celsius

Celsius and Kelvin are two commonly used temperature scales in the field of science and everyday life. The Celsius scale, also known as the centigrade scale, is named after the Swedish astronomer Anders Celsius. It is based on the concept of dividing the range between the freezing and boiling points of water into 100 equal intervals. The freezing point of water is defined as 0 degrees Celsius, while the boiling point is defined as 100 degrees Celsius at standard atmospheric pressure.

The Celsius scale is commonly used in weather forecasts, household thermometers, and cooking, while the Kelvin scale is primarily used in scientific experiments, thermodynamics, and calculations involving gases.

## About Rankine

Rankine is a unit of temperature measurement commonly used in engineering and thermodynamics. It is named after the Scottish engineer and physicist William John Macquorn Rankine, who made significant contributions to the field of thermodynamics in the 19th century. The Rankine scale is an absolute temperature scale, similar to the Kelvin scale, but with a different zero point.

The Rankine scale is based on the Fahrenheit scale, with the zero point set at absolute zero (-459.67°F). This means that the Rankine scale has the same size degree as the Fahrenheit scale, but starts at a different point. To convert between Rankine and Celsius, one must first convert from Celsius to Kelvin by adding 273.15, and then convert from Kelvin to Rankine by multiplying by 1.8. The formula for this conversion is: Rankine = (Celsius + 273.15) × 1.8.

While the Rankine scale is not commonly used in everyday life, it is widely used in engineering and thermodynamics, particularly in the United States. It is often used in calculations involving temperature differentials, such as in the study of heat transfer and energy systems. Understanding the Rankine scale and its conversion to Celsius is important for engineers and scientists working in these fields, as it allows for accurate and consistent temperature measurements and calculations.
