°R

100 °C = 671.67 °R

°R = (°C + 273.15) × 9/5

Celsius to Rankine: To convert celsius to rankine, apply °R = (°C + 273.15) × 9/5. Unlike linear unit conversions, celsius and rankine use different zero points, so a fixed multiplier is not sufficient.

How to Convert Celsius to Rankine

Converting between celsius and rankine requires both a scale factor and an offset because the two scales use different zero points. The formula below handles both adjustments.

Conversion Formula

  • Celsius to Rankine: °R = (°C + 273.15) × 9/5
  • Rankine to Celsius: °C = (°R × 5/9) − 273.15

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.

FAQ

What is the Rankine scale?

Rankine is an absolute temperature scale like Kelvin, but uses Fahrenheit-sized degrees. Zero Rankine equals absolute zero (-273.15 °C or -459.67 °F).

How do you convert Celsius to Rankine?

Add 273.15 to the Celsius value to get Kelvin, then multiply by 9/5. For example, 5.3 °C = (5.3 + 273.15) × 9/5 = 500.67 °R.

Where is the Rankine scale used?

Rankine is primarily used in thermodynamic calculations in the United States, particularly in engineering fields that work with the Fahrenheit system.

What is 0 °C in Rankine?

0 °C equals 491.67 °R. This is the freezing point of water on the Rankine scale.

What is 100 °C in Rankine?

100 °C equals 671.67 °R. This is the boiling point of water on the Rankine scale.

How do you convert rankine back to celsius?

Use the inverse formula: °C = (°R × 5/9) − 273.15.

Why isn't celsius-to-rankine a simple multiplication?

Celsius and Rankine use different zero points, so the relationship includes both a scale factor and an offset. The scale factor alone gives the rate of change but not the absolute value.
