Converting Rankine to Kelvin

Converting Rankine to Kelvin bridges the gap between US engineering standards and international scientific measurements, translating between the two absolute temperature scales.

Mathematical Relationship

The mathematical relation between Rankine and Kelvin is: K = °R × 5/9. To convert a temperature in Rankine to Kelvin, multiply the Rankine value by 5/9.

Unit Definitions

Rankine

The Rankine scale (symbol: °R) is an absolute temperature scale named after Scottish engineer William John Macquorn Rankine, who proposed it in 1859. The zero point of the Rankine scale is absolute zero, and a one-degree change in Rankine is equal to a one-degree change in Fahrenheit.

Kelvin

The Kelvin (symbol: K) is the base unit of temperature in the International System of Units (SI). It is an absolute temperature scale where zero represents absolute zero, the theoretical point at which all thermal motion ceases.

Historical Context

Both scales were developed in the 19th century to provide absolute temperature references for scientific and engineering calculations. The Kelvin scale uses the same increment as the Celsius scale, while the Rankine scale uses the same increment as the Fahrenheit scale.
