About the Rankine Scale
The Rankine scale (°R) is an absolute temperature scale used primarily in engineering systems in the United States. It's similar to the Kelvin scale, but uses Fahrenheit-sized degrees instead of Celsius-sized degrees. Zero Rankine (0 °R) represents absolute zero, the theoretical point where all molecular motion stops.
Key Rankine Facts
- Absolute Zero: 0 °R = -459.67°F = -273.15°C = 0 K
- Water Freezes: 491.67 °R = 32°F = 0°C = 273.15 K
- Room Temperature: ~527.67 °R = 68°F = 20°C = 293.15 K
- Water Boils: 671.67 °R = 212°F = 100°C = 373.15 K
- Named After: William John Macquorn Rankine
- Common Use: U.S. engineering applications, thermodynamics
