Rankine to Celsius (°R to °C)
Convert °R to °C — Temperature converter
Also written as R to C.
Converting Rankine to Celsius uses the formula °C = (°R − 491.67) × 5/9. Both are temperature scales that measure how hot or cold something is, so the change is a formula rather than a single multiplier. A few reference points: 0 °R = -273.15 °C, 37 °R = -252.594444 °C, and 100 °R = -217.594444 °C.
