Rankine
Definition
Rankine (R) is an absolute temperature scale used in thermodynamics, particularly in engineering fields. It is similar to the Kelvin scale but uses Fahrenheit as its incremental unit. The Rankine scale starts at absolute zero (0 R), the theoretical point at which all molecular motion ceases. The symbol for Rankine is R or °R.
History/Origin
The Rankine scale was introduced in 1859 by Scottish engineer and physicist William John Macquorn Rankine. It was developed to provide an absolute temperature scale for engineering applications while maintaining compatibility with the Fahrenheit scale. The Rankine scale became popular in fields like thermodynamics and aeronautical engineering, where precise temperature calculations are critical.
Current Use
Rankine is primarily used in engineering applications within the United States, especially in thermodynamics and aerodynamics. It is also employed in calculations involving heat transfer, combustion, and power cycles. Despite its limited everyday use, it remains a valuable unit in specific scientific and industrial contexts.
Kelvin
Definition
Kelvin (K) is the SI base unit of thermodynamic temperature. It is an absolute temperature scale, starting at absolute zero (0 K), where all molecular motion theoretically ceases. Unlike Rankine, the Kelvin scale uses Celsius as its incremental unit. Kelvin does not include a degree symbol (°), and its measurements align directly with the laws of thermodynamics.
History/Origin
The Kelvin scale was developed in the mid-19th century by William Thomson, also known as Lord Kelvin. It was designed as an absolute temperature scale to aid in scientific research, particularly in thermodynamics. Kelvin’s contributions to the understanding of energy and heat solidified the scale’s importance in the scientific community.
Current Use
Kelvin is widely used in scientific and engineering disciplines across the globe. It is essential for calculations in physics, chemistry, and astronomy, where precise temperature measurements are required. Kelvin is also the standard for international scientific collaborations and research.

Quick Reference Conversion Table
Step-by-Step Conversion Instructions
Example: Convert 527.67 R to Kelvin
Start with the formula: [ K = \frac{R}{1.8} ]
Divide the Rankine value by 1.8: [ K = \frac{527.67}{1.8} ]
Perform the calculation: [ K = 293.15 ]
Result: 527.67 R equals 293.15 K.
Practical Examples
Example 1: Freezing Point of Water
Rankine: 491.67 R
Conversion: [ K = \frac{491.67}{1.8} = 273.15 K ]
Result: 491.67 R equals 273.15 K, the freezing point of water.
Example 2: Boiling Point of Water
Rankine: 671.67 R
Conversion: [ K = \frac{671.67}{1.8} ] [ K = 373.15 K ]
Result: 671.67 R equals 373.15 K, the boiling point of water.
