Enter any temperature value in Rankine (must be 0 or greater)

Quick Reference:

  • Absolute zero is 0°R (0K)
  • Water freezes at 491.67°R (273.15K)
  • Room temperature is about 527.67-536.67°R (293-298K)
  • Body temperature is 558.27°R (310.15K)
  • Water boils at 671.67°R (373.15K)

The Rankine to Kelvin converter is a simple yet essential tool for engineers, scientists, and students who frequently work with thermodynamic calculations. Rankine (°R) and Kelvin (K) are both absolute temperature scales used primarily in scientific fields, particularly in thermodynamics and engineering applications.

Understanding Rankine and Kelvin Scales

The Rankine scale, denoted as °R, is an absolute temperature scale primarily used in the United States, particularly in engineering fields involving thermodynamics. It is similar to the Fahrenheit scale but starts from absolute zero.

The Kelvin scale, denoted as K, is the standard international unit of temperature measurement used in scientific research and engineering worldwide. It is based on the Celsius scale but begins at absolute zero.

Rankine to Kelvin Conversion Formula

$$ K = \frac{5}{9} \times R $$

To convert a temperature from Rankine to Kelvin, simply multiply the Rankine temperature by 5/9. This formula ensures accurate conversion, as both scales are absolute and differ only by a constant factor.

How to Use the Rankine to Kelvin Converter

Using the Rankine to Kelvin converter is straightforward:

  • Enter the temperature value in Rankine (°R) in the input field.
  • Click the "Convert" button to calculate the equivalent temperature in Kelvin (K).
  • The converted temperature will be displayed along with a descriptive label indicating how the temperature feels.

The tool also includes a reset button, allowing you to clear previous inputs and results quickly.

Practical Applications of Rankine and Kelvin Scales

Both Rankine and Kelvin scales are used in various scientific and engineering fields. Some of the most common applications include:

  • Thermodynamics: Kelvin and Rankine are widely used in equations related to heat, work, and energy transfer.
  • Chemical Engineering: Many industrial processes require temperature calculations in absolute scales.
  • Space Science: In astrophysics and space exploration, Kelvin is the preferred unit due to its universality.
  • Climate Studies: Scientists use the Kelvin scale when studying Earth's temperature and climate patterns.
