How to Convert Rankine to Kelvin
The conversion between Rankine and kelvin is not linear or involves a specific formula. Please use the calculator above for an accurate conversion.
To convert from Rankine to the base unit, the formula is: y = Rankine * (5/9)
To convert from the base unit to kelvin, the formula is: y = base_unit_value

Rankine
Rankine (°R) is an absolute temperature scale used primarily in engineering, where 0°R represents absolute zero and each degree Rankine is equivalent to one degree Fahrenheit.
History/Origin
The Rankine scale was introduced by William John Macquorn Rankine in 1859 as an absolute temperature scale based on the Fahrenheit degree, primarily used in the United States for thermodynamic calculations.
Current Use
Today, the Rankine scale is mainly used in certain engineering fields within the United States, especially in thermodynamics and heat transfer calculations, but it is largely replaced by the Kelvin scale in scientific contexts.
Kelvin
The kelvin (K) is the base unit of temperature in the International System of Units (SI), defined as 1/273.16 of the thermodynamic temperature of the triple point of water.
History/Origin
The kelvin was established in 1848 by Lord Kelvin (William Thomson) as a temperature scale based on absolute zero, replacing earlier thermodynamic temperature scales. It was officially adopted as an SI base unit in 1960.
Current Use
The kelvin is used worldwide in scientific and engineering contexts to measure thermodynamic temperature, especially in physics, chemistry, and related fields, providing a standard for temperature measurement without negative values.
