Temperature Scale Comparison Thermometer Rankine (°R) Fahrenheit (°F) °R = °F + 459.67 °F = °R - 459.67 Absolute Zero

Convert between Rankine (°R) and Fahrenheit (°F) temperature scales in both directions with precision. The Rankine scale is an absolute thermodynamic temperature scale using Fahrenheit degree intervals, where absolute zero equals 0°R.

Conversion Formulas

°F = °R - 459.67
°R = °F + 459.67

Example Calculations

Rankine to Fahrenheit:
Convert 671.67°R to Fahrenheit:
°F = 671.67 - 459.67 = 212°F

Fahrenheit to Rankine:
Convert 32°F to Rankine:
°R = 32 + 459.67 = 491.67°R
Note: The Rankine scale starts at absolute zero (0°R = -459.67°F), making it useful in engineering calculations where absolute temperature values are required. This calculator supports bidirectional conversion with adjustable decimal precision.
