Selected °C values converted to °R using the exact offset formulas from this tool.

Exact offset formulas in both directions, plus a worked example.

°R = (°C + 273.15) × 9/5

°C = °R × 5/9 − 273.15

Add 273.15 to Celsius, multiply by 9/5 to get Rankine.

Multiply Rankine by 5/9, then subtract 273.15 to get Celsius.

Example: convert 37 °C to °R

37 °C → 558.27 °R (celsius to rankine)

Short background on the units used in this conversion.

The Celsius scale sets the freezing point of water at 0° and the boiling point at 100° at standard atmospheric pressure.

Celsius is the everyday temperature scale in most countries, on weather forecasts, and in science alongside kelvin.

The Rankine scale is an absolute Fahrenheit-scale system: 0°R is absolute zero and one Rankine degree equals one Fahrenheit degree.

Rankine is used in some US engineering fields, especially thermodynamics and aerospace calculations.

How do I convert celsius to rankine?

Add 273.15 to Celsius, multiply by 9/5 to get Rankine. The formula is °R = (°C + 273.15) × 9/5.

What is a useful reference point?

0 °C equals 491.67 °R (for example, water freezes at 0°C = 32°F = 273.15 K).
