Rankine (°R)

Rankine is a less common absolute temperature scale that combines the Fahrenheit scale size with the absolute zero reference point of Kelvin. It’s sometimes used in engineering contexts, particularly in the United States.

Characteristics

  • Absolute temperature scale
  • Degree size: same as Fahrenheit (5/9 K per °R)
  • Absolute zero: 0°R (same as 0 K)
  • Water freezes at: 491.67°R
  • Water boils at: 671.67°R
  • Rarely used in modern practice

Conversion Formulas

  • To Kelvin: K = °R × 5/9
  • To Celsius: °C = (°R - 491.67) × 5/9
  • To Fahrenheit: °F = °R - 459.67
  • From Kelvin: °R = K × 9/5

Examples

  • Absolute zero: 0°R = 0 K
  • Room temperature: ~527°R
  • Body temperature: ~559°R
