Unit Explanations
KelvinK
Source UnitThe Kelvin (K) is the base unit of temperature in the International System of Units (SI). It is defined by taking the fixed numerical value of the Boltzmann constant, k, to be 1.380649×10^-23 when expressed in the unit J K^-1, which is equal to kg m^2 s^-2 K^-1. The Kelvin is used to measure thermodynamic temperature and is one of the seven SI base units. Unlike Celsius, the Kelvin scale is an absolute scale starting from absolute zero, the point at which all molecular motion ceases.
Current Use
The Kelvin is widely used in scientific research, particularly in physics and chemistry, where precise temperature measurements are crucial. It is also used in engineering applications and space sciences, due to its absolute nature. The Kelvin is vital in any field where temperature plays a critical role, from material science to cosmology.
Fun Fact
The Kelvin scale does not use degrees, unlike Celsius and Fahrenheit.
Interval Degree Rankine°R
Target UnitThe interval degree Rankine (°R) is a temperature scale primarily utilized in thermodynamic calculations. It is defined as having the same incremental value as the Fahrenheit scale, whereby a change of 1 degree Rankine is equivalent to a change of 1 degree Fahrenheit. The Rankine scale starts at absolute zero, which is 0 °R, and its zero point corresponds to -459.67 °F. It is particularly useful in engineering fields, where temperature differences rather than absolute values are frequently required.
Current Use
The interval degree Rankine is primarily used in mechanical engineering and thermodynamic calculations, especially in the United States. It is favored in certain industries where systems operate using the Fahrenheit scale. The Rankine scale provides a straightforward method for calculating temperature differences in energy systems, making it a valuable tool for engineers working on heat engines, refrigeration, and HVAC systems.
Fun Fact
The Rankine scale is named after William John Macquorn Rankine, who also contributed significantly to the fields of thermodynamics and engineering.

Definition
The Kelvin (K) is the base unit of temperature in the International System of Units (SI). It is defined by taking the fixed numerical value of the Boltzmann constant, k, to be 1.380649×10^-23 when expressed in the unit J K^-1, which is equal to kg m^2 s^-2 K^-1. The Kelvin is used to measure thermodynamic temperature and is one of the seven SI base units. Unlike Celsius, the Kelvin scale is an absolute scale starting from absolute zero, the point at which all molecular motion ceases.
History & Origin
The Kelvin scale was developed in the mid-19th century by Lord Kelvin, a prominent physicist, who proposed an absolute temperature scale independent of the properties of a particular substance. This concept of absolute zero provided a uniform scale for comparing temperatures, based on the laws of thermodynamics.
Etymology: Named after Lord Kelvin, born William Thomson, who was a physicist and engineer.
Current Use
The Kelvin is widely used in scientific research, particularly in physics and chemistry, where precise temperature measurements are crucial. It is also used in engineering applications and space sciences, due to its absolute nature. The Kelvin is vital in any field where temperature plays a critical role, from material science to cosmology.
💡 Fun Facts
- •The Kelvin scale does not use degrees, unlike Celsius and Fahrenheit.
- •Absolute zero, 0 K, is theoretically the lowest temperature possible.
- •The Kelvin scale is named after a person, unlike most other SI units.

Interval Degree Rankine
temperature • Non-SI
Definition
The interval degree Rankine (°R) is a temperature scale primarily utilized in thermodynamic calculations. It is defined as having the same incremental value as the Fahrenheit scale, whereby a change of 1 degree Rankine is equivalent to a change of 1 degree Fahrenheit. The Rankine scale starts at absolute zero, which is 0 °R, and its zero point corresponds to -459.67 °F. It is particularly useful in engineering fields, where temperature differences rather than absolute values are frequently required.
History & Origin
The Rankine scale was developed by Scottish engineer William John Macquorn Rankine in the mid-19th century as part of his work on thermodynamics. Rankine's goal was to create a temperature scale that was absolute and based on the Fahrenheit scale, allowing for easy conversion and calculation in thermodynamic processes. The scale was adopted for use in various engineering disciplines as it improved upon the limitations of other temperature scales.
Etymology: The term 'Rankine' derives from the surname of William John Macquorn Rankine, who was a prominent figure in thermodynamics and engineering during the 19th century.
Current Use
The interval degree Rankine is primarily used in mechanical engineering and thermodynamic calculations, especially in the United States. It is favored in certain industries where systems operate using the Fahrenheit scale.
