Enter any temperature value in Rankine (must be 0 or greater)

Quick Reference:

  • Absolute zero is 0°R (-273.15°C)
  • Water freezes at 491.67°R (0°C)
  • Room temperature is about 527.67-536.67°R (20-25°C)
  • Body temperature is 557.67°R (37°C)
  • Water boils at 671.67°R (100°C)

The Rankine to Celsius Converter is a simple yet powerful tool that allows you to quickly and accurately convert temperatures from Rankine (°R) to Celsius (°C). This conversion is particularly useful in scientific and engineering applications where absolute temperature scales are frequently used.

What is Rankine?

Rankine (°R) is an absolute temperature scale used mainly in engineering fields, particularly in thermodynamics. It is similar to the Kelvin scale but is based on the Fahrenheit system. The Rankine scale starts at absolute zero (0°R), which is equivalent to -459.67°F or -273.15°C.

How to Convert Rankine to Celsius

The formula to convert Rankine to Celsius is:

$$ \text{°C} = (\text{°R} - 491.67) \times \frac{5}{9} $$

This means that you need to subtract 491.67 from the given Rankine value and then multiply the result by 5/9 to get the equivalent temperature in Celsius.

Step-by-Step Conversion Example

Let’s convert 600°R to Celsius:

  • Start with the given temperature: 600°R
  • Subtract 491.67: 600 - 491.67 = 108.33
  • Multiply by 5/9: 108.33 × 5/9 = 60.18°C

Thus, 600°R is approximately 60.18°C.

Why Use the Rankine to Celsius Converter?

There are several reasons why using a converter tool is beneficial:

  • Accuracy: Avoid calculation errors with instant and precise conversions.
  • Convenience: Quickly convert temperatures without manual math.
  • Educational: Understand temperature relationships between Rankine and Celsius.
