Rankine to Celsius Conversion

The Rankine and Celsius scales are both used to measure temperature. While Celsius is widely adopted internationally, Rankine is an absolute temperature scale primarily used in engineering, particularly in thermodynamic calculations within the United States.

Understanding the Rankine Scale

The Rankine scale is an absolute thermodynamic temperature scale, meaning its zero point coincides with absolute zero, the lowest possible temperature. It employs degrees Rankine (°R) as its unit.

  • Key Characteristics:
  • Absolute zero is defined as 0°R.
  • One degree Rankine is equivalent in magnitude to one degree Fahrenheit.

Understanding the Celsius Scale

The Celsius scale is another widely used temperature scale. It's based on the Celsius degree (°C), where 0°C represents the freezing point of water, and 100°C signifies the boiling point of water at standard atmospheric pressure.

The Conversion Formula

To convert a temperature from Rankine to Celsius, use the following formula:

**Celsius (°C) = (Rankine (°R) - 32) * (5/9)**

Example Conversion

Let's convert 600°R to Celsius:

  1. **Apply the formula:** Celsius = (600°R - 32) * (5/9)
  2. **Calculate:** Celsius = (568) * (5/9) = 315.56 °C

Therefore, 600°R is equivalent to 315.56°C.
