Understanding Temperature Scales

Key Temperature Points

Temperature Point Rankine (°R) Kelvin (K)
Absolute Zero 0 0
Water Freezing Point 491.67 273.15
Water Boiling Point 671.67 373.15

Conversion Formula

K = °R × (5/9)

To convert from Rankine to Kelvin, multiply the temperature in Rankine by 5/9. This conversion factor comes from the relationship between the size of the degree increments in each scale.

About These Temperature Scales

Both Rankine and Kelvin are absolute temperature scales, meaning they start at absolute zero (the lowest possible temperature). The main difference is that Rankine uses Fahrenheit-sized degrees, while Kelvin uses Celsius-sized degrees.

The Kelvin scale is the SI base unit for temperature and is widely used in scientific calculations and measurements. The Rankine scale, while less common, is sometimes used in engineering calculations, particularly in English-speaking countries.
