Rankine to Celsius Calculator

Rankine to Celsius Calculator

Looking for a quick and accurate way to convert Rankine to Celsius? Our Rankine to Celsius Calculator provides instant, reliable results with just one click. Whether you are a student, scientist, engineer, or researcher, this tool makes it easy to switch between two important temperature scales used in both academic studies and advanced engineering applications.

Understanding Rankine and Celsius

Rankine (°R or °Ra): Rankine is an absolute temperature scale, similar to Kelvin, but based on Fahrenheit increments.
On this scale:
Absolute zero = 0 °R
Water freezes at 491.67 °R
Water boils at 671.67 °R
Rankine is widely used in the United States, especially in thermodynamics, aerospace engineering, and energy sector calculations.

Celsius (°C): Celsius, also known as the Centigrade scale, is the most common temperature unit worldwide.
On this scale:
Water freezes at 0°C
Water boils at 100°C (at standard atmospheric pressure)
Celsius is used in weather reports, education, cooking, healthcare, and science.

👉 Conversion Value: Since Rankine is tied to Fahrenheit, converting it to Celsius requires a two-step adjustment.

Formula to Convert Rankine to Celsius

Examples of Conversion

Convert 491.67 °R to Celsius

✅ So, 491.67 °R = 0°C (freezing point of water).

Convert 671.67 °R to Celsius

✅ So, 671.67 °R = 100°C (boiling point of water).

Convert 558 °R to Celsius

✅ So, 558 °R = 36.85°C (close to average human body temperature).

Convert 419.67 °R to Celsius

✅ So, 419.67 °R = -40°C (a rare point where Celsius and Fahrenheit overlap).

Convert 900 °R to Celsius

✅ So, 900 °R = 226.85°C (very high temperature useful in industrial processes).
