Kelvin
Definition
Kelvin (K) is the SI base unit for thermodynamic temperature. It is an absolute temperature scale that begins at absolute zero, the theoretical point at which molecular motion ceases. Unlike other temperature scales, Kelvin does not use a degree symbol (°). Kelvin is directly related to the Celsius scale, where 0°C is equivalent to 273.15 K.
History/Origin
The Kelvin scale was introduced in the mid-19th century by William Thomson, later known as Lord Kelvin. He established the scale based on the laws of thermodynamics, defining absolute zero (0 K) as the point where entropy reaches its minimum value. This scale provides a fundamental reference point for temperature measurements and calculations in scientific disciplines.
Current Use
Kelvin is widely used in scientific and engineering fields, particularly in physics, chemistry, and space exploration. It is essential for calculations involving thermodynamics, such as entropy and enthalpy. Kelvin is also employed in defining the color temperature of light sources and in various global scientific research applications.
Rankine
Definition
Rankine (R) is an absolute temperature scale used primarily in engineering and thermodynamics. It is similar to Kelvin but uses Fahrenheit-sized increments. The Rankine scale starts at absolute zero, making it an absolute scale, and is denoted as R or °R.
History/Origin
The Rankine scale was developed by Scottish engineer and physicist William John Macquorn Rankine in the mid-19th century. It was introduced to provide a convenient absolute temperature scale compatible with the Fahrenheit system. This made it particularly useful in engineering applications within countries that primarily used Fahrenheit.
Current Use
The Rankine scale is predominantly used in engineering and thermodynamic studies in the United States, especially in the context of aerospace and energy industries. Its compatibility with Fahrenheit-based systems makes it a preferred choice for certain engineering calculations and analyses.

Step-by-Step Conversion Instructions
Example: Convert 300 K to Rankine
Start with the formula: [ R = K × \frac{9}{5} ]
Multiply the Kelvin value by 9/5: [ R = 300 × \frac{9}{5} ]
Perform the calculation: [ R = 300 × 1.8 = 540 R ]
Result: 300 K equals 540 R.
Practical Examples
Example 1: Freezing Point of Water
Kelvin: 273.15 K
Conversion: [ R = 273.15 × \frac{9}{5} = 491.67 R ]
Result: 273.15 K equals 491.67 R, representing the freezing point of water.
Example 2: Boiling Point of Water
Kelvin: 373.15 K
Conversion: [ R = 373.15 × \frac{9}{5} ] [ R = 671.67 R ]
Result: 373.15 K equals 671.67 R, representing the boiling point of water.
