How to Convert Kelvin to Rankine
To convert kelvin (K) to rankine (°R), apply the thermodynamic scale offset formula rather than a single multiplication factor because the two temperature scales have different zero points.
You can use this standard formula to convert kelvin to rankine:
Each temperature reading in kelvin is scaled and shifted by the zero-point offset to obtain the exact temperature in rankine.
For example, here's how to convert 5 K to rankine using the formula above:
How Many Rankine Are in a Kelvin?
On the Kelvin scale, a reading of 1 K corresponds to 1.8 °R on the Rankine scale.
Our kelvin to rankine calculator automatically converts your temperature measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Kelvin and rankine are both units used to measure temperature. Keep reading to learn more about each unit.
What Is a Kelvin?
Base SI thermodynamic temperature scale starting at absolute zero (0 K = -273.15 °C). It serves as a primary reference unit for measuring temperature across scientific and practical applications. [1]
The kelvin is classified as an International System of Units (SI) unit of temperature. Kelvin can be abbreviated as K; for example, 1 kelvin can be written as 1 K.
When working with kelvin (K) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, kelvin (K) are widely used across standard temperature applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
What Is a Rankine?
Absolute thermodynamic temperature scale with Fahrenheit-sized degrees (0 °R = -459.67 °F). It serves as a primary reference unit for measuring temperature across scientific and practical applications. [2]
The rankine is classified as a US customary and imperial unit of temperature. Rankine can be abbreviated as °R; for example, 1 rankine can be written as 1 °R.
When working with rankine (°R) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, rankine (°R) are widely used across standard temperature applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
When converting temperature between kelvin (K) and rankine (°R), keep full floating-point precision (1 K = 1.8 °R; 1 °R = 0.5555556 K) during intermediate calculations and round only the final rankine figure to match your instrument tolerance.
