Understanding Rankine and Kelvin

Rankine (°R or °Ra): The Rankine scale is an absolute temperature scale that uses the same degree intervals as Fahrenheit but starts at absolute zero (0 °R).
On this scale:
Water freezes at 491.67 °R
Water boils at 671.67 °R
Rankine is commonly used in the United States, especially in thermodynamics, aerospace engineering, and power generation industries.

Kelvin (K): Kelvin is the SI base unit of temperature and is widely used worldwide in science, physics, astronomy, and engineering.
Like Rankine, Kelvin also begins at absolute zero (0 K).
On this scale:
Water freezes at 273.15 K
Water boils at 373.15 K

👉 Conversion Value: Because both Rankine and Kelvin are absolute scales, their conversion is a simple proportional relationship.

Formula to Convert Rankine to Kelvin

Examples of Conversion

Convert 0 °R to Kelvin

✅ So, 0 °R = 0 K (absolute zero in both scales).

Convert 180 °R to Kelvin

✅ So, 180 °R = 100 K (extremely low cryogenic temperature).

Convert 491.67 °R to Kelvin

✅ So, 491.67 °R = 273.15 K (freezing point of water).

Convert 671.67 °R to Kelvin

✅ So, 671.67 °R = 373.15 K (boiling point of water).

Convert 900 °R to Kelvin

✅ So, 900 °R = 500 K (high temperature, useful in industrial and scientific studies).

Convert 1500 °R to Kelvin

✅ So, 1500 °R = 833.33 K (very high heat conditions in aerospace and power plants).
