Rankine to Celsius: To convert rankine to celsius, apply °C = (°R × 5/9) − 273.15. Unlike linear unit conversions, rankine and celsius use different zero points, so a fixed multiplier is not sufficient.
How to Convert Rankine to Celsius
Converting between rankine and celsius requires both a scale factor and an offset because the two scales use different zero points. The formula below handles both adjustments.
Conversion Formula
- Rankine to Celsius:
°C = (°R × 5/9) − 273.15 - Celsius to Rankine:
°R = (°C + 273.15) × 9/5

Understanding the Units
What is a Celsiu?
The degree Celsius is a derived SI unit of temperature where 0 °C corresponds to the freezing point of water and 100 °C to the boiling point at standard atmospheric pressure.
Named after Anders Celsius (1701–1744), Swedish astronomer who proposed the original scale in 1742.
Common contexts: weather, cooking, science.
