How to Convert Rankine to Celsius
To convert Rankine (°R) to Celsius (°C), use the formula: °C = (°R − 491.67) × 5/9.
For example, to convert 5 °R to °C: 5 °R = -270.37 °C. Similarly, 10 °R = -267.59 °C, 25 °R = -259.26 °C, and 100 °R = -217.59 °C.
To convert in the other direction, 1 °C = 493.47 °R. Simply enter your value in either field above for instant bi-directional conversion.
What is a Rankine?
Rankine (°R) is an absolute temperature scale using Fahrenheit-sized degrees, starting at absolute zero. Rankine is used in some US engineering contexts, particularly in thermodynamics.
What is a Celsius?
Celsius (°C) is a temperature scale where water freezes at 0° and boils at 100° at standard pressure. Celsius is used by most countries worldwide for weather, cooking, and science.
