\[C = \frac{5}{9}R - 273.15\]
Variables
Rtemperature in degrees Rankine (°R)
Ctemperature in degrees Celsius (°C)
Description
What is this formula?
This formula converts a temperature from degrees Rankine (°R) to degrees Celsius (°C). Rankine is an absolute temperature scale based on Fahrenheit increments, while Celsius is the standard scale used in science and engineering worldwide.
When to use it
Use this formula whenever a temperature expressed in Rankine must be converted to Celsius for scientific calculations, engineering reports, thermal analysis, or international technical documentation.
Example
Convert 540 °R to Celsius.
Data:
R = 540 °R
Formula:
C = (5*R/9) - 273.15
Substitution:
C = (5*540/9) - 273.15
Result:
C = 26.85 °C
