Absolute Temperature in Rankine: All You Need to Know

What is Absolute Temperature in Rankine?

Absolute temperature is a measure of temperature that is independent of the properties of any particular substance. It is based on the concept of absolute zero, which is the theoretical lowest temperature possible. Absolute zero is defined as -273.15 degrees Celsius or -459.67 degrees Fahrenheit.

The Rankine scale is a temperature scale that is based on absolute zero. It is named after William John Macquorn Rankine, a Scottish physicist and engineer who proposed the scale in 1859. The Rankine scale is defined by the following equation:

°R = °F + 459.67

where:

• °R is the temperature in degrees Rankine
• °F is the temperature in degrees Fahrenheit

Why is Absolute Temperature in Rankine Important?

Absolute temperature is important because it allows us to compare the temperatures of different substances on a common scale. This is useful for a variety of applications, such as:

• Thermodynamics: Absolute temperature is used to calculate the efficiency of heat engines and other thermodynamic systems.
• Chemistry: Absolute temperature is used to calculate the rates of chemical reactions.
• Engineering: Absolute temperature is used to design and operate industrial processes.

How to Convert Temperatures to and from Rankine

To convert a temperature from degrees Fahrenheit to degrees Rankine, simply add 459.67 to the Fahrenheit temperature. For example, to convert 70 degrees Fahrenheit to degrees Rankine, add 459.67 to 70 to get 529.67 degrees Rankine.

To convert a temperature from degrees Rankine to degrees Fahrenheit, simply subtract 459.67 from the Rankine temperature. For example, to convert 529.67 degrees Rankine to degrees Fahrenheit, subtract 459.67 from 529.67 to get 70 degrees Fahrenheit.
