Rankine to Kelvin Conversion: The Ultimate Guide for Temperature Conversions

In the realm of thermodynamics and temperature measurements, the conversion between Rankine (Ra) and Kelvin (K) is crucial for accurate calculations and understanding. This comprehensive guide delves into the intricacies of Rankine to Kelvin conversion, providing a step-by-step approach, useful tables, and practical applications.

Rankine and Kelvin Units: A Brief Overview

The Rankine temperature scale is predominantly used in the United States, while the Kelvin scale is the primary unit of temperature in the International System of Units (SI) and scientific communities worldwide.

• Rankine: The Rankine scale is based on the Fahrenheit scale but uses the absolute zero as its starting point. Absolute zero, defined as -459.67 °F (-273.15 °C), is the point at which all molecular motion ceases.

• Kelvin: The Kelvin scale is an absolute temperature scale that takes its name from Lord Kelvin, a Scottish physicist. Absolute zero is defined as 0 K, and the size of one degree Kelvin is identical to that of one degree Celsius.

Formula for Rankine to Kelvin Conversion

Converting Rankine to Kelvin is straightforward using the following formula:

K = Ra × 5/9

where:

• K is the temperature in Kelvin
• Ra is the temperature in Rankine
