What is the Rankine to Celsius Converter?
The Rankine ($^\circ$R) to Celsius ($^\circ$C) converter translates advanced thermodynamics from American aerospace data back into the standard metric format utilized by international civilians and laboratories.
How It Works (Formula)
This multi-step formula first converts Rankine to absolute Kelvin by compressing the degrees by $5/9$. From that absolute Kelvin value, it then subtracts the freezing point of water (273.15) to arrive at the relative Celsius scale.
$$ T_{(^\circ\text{C})} = (T_{(^\circ\text{R})} - 491.67) \times \frac{5}{9} $$

How to Use It
Enter the thermodynamic temperature in Rankine ($^\circ$R). The calculator applies the shift and compression, immediately outputting the equivalent in Celsius ($^\circ$C). For example, exactly 491.67 $^\circ$R equals 0 $^\circ$C.
