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.
Degree Rankine°R
Target UnitThe degree Rankine (°R) is an absolute temperature scale that is primarily used in thermodynamics and engineering, particularly in the United States. The Rankine scale is based on the absolute zero of temperature, similar to the Kelvin scale, but its increments are equivalent to those of the Fahrenheit scale. This means that a temperature change of 1 °R is equal to a temperature change of 1 °F. The Rankine scale is particularly useful in calculations involving thermodynamic cycles and processes, where absolute temperature is essential.
Current Use
The Rankine scale is used primarily in engineering fields, particularly in thermodynamics and fluid mechanics. It is especially relevant in calculations involving heat engines, refrigeration cycles, and other thermodynamic systems where absolute temperature measurements are crucial.
Fun Fact
The Rankine scale is not widely used outside the U.S., where Celsius and Kelvin are more prevalent.

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.

temperature • Non-SI
Definition
The degree Rankine (°R) is an absolute temperature scale that is primarily used in thermodynamics and engineering, particularly in the United States. The Rankine scale is based on the absolute zero of temperature, similar to the Kelvin scale, but its increments are equivalent to those of the Fahrenheit scale. This means that a temperature change of 1 °R is equal to a temperature change of 1 °F. The Rankine scale is particularly useful in calculations involving thermodynamic cycles and processes, where absolute temperature is essential.
History & Origin
The Rankine scale was developed by Scottish engineer William John Macquorn Rankine in the mid-19th century. His work focused on steam engines and thermodynamics, which required a practical temperature scale for engineering applications. Rankine's proposal was to create a temperature scale that would complement the Fahrenheit scale, allowing engineers to work with absolute temperatures.
Etymology: The term 'Rankine' is derived from the name of its creator, William John Macquorn Rankine.
Current Use
The Rankine scale is used primarily in engineering fields, particularly in thermodynamics and fluid mechanics. It is especially relevant in calculations involving heat engines, refrigeration cycles, and other thermodynamic systems where absolute temperature measurements are crucial.
💡 Fun Facts
- •The Rankine scale is not widely used outside the U.S., where Celsius and Kelvin are more prevalent.
- •The Rankine scale's increments are equal to Fahrenheit degrees, making it convenient for engineers who work with Fahrenheit.
- •William Rankine was also a pioneer in the field of thermodynamics, contributing significantly to steam engine design.
