Rankine to Fahrenheit Conversion

This guide provides a comprehensive overview of converting temperatures between the Rankine and Fahrenheit scales.

Understanding the Rankine Scale

The Rankine scale, named after Scottish engineer William John Macquorn Rankine, is an absolute thermodynamic temperature scale. Unlike the Fahrenheit scale, which is relative, Rankine's zero point aligns with absolute zero (the lowest possible temperature).

  • 0°R = -459.67°F
  • Freezing point of water: 491.67°R
  • Boiling point of water: 671.67°R

Understanding the Fahrenheit Scale

The Fahrenheit scale is a temperature scale commonly used in the United States. It defines the freezing point of water as 32°F and the boiling point of water as 212°F at standard atmospheric pressure.

Rankine to Fahrenheit Conversion Formula

The conversion from Rankine to Fahrenheit is straightforward:

Fahrenheit (°F) = Rankine (°R) - 459.67

Example

Let's convert a temperature of 550°R to Fahrenheit:

  1. **Apply the formula:** Fahrenheit = 550R - 459.67
  2. **Calculate:** Fahrenheit = 90.33°F
