Use this page to convert rankine values into celsius, with background details, formulas, a worked example, and a quick conversion table.

This conversion uses an offset formula rather than a single multiplier because the temperature scales start from different zero points.

deg R to deg C: Apply the scale formula and then add or remove the required offset.

Example: 25 deg R = -259.261111111111 deg C

Rankine starts at absolute zero, and one Rankine degree is the same interval as one Fahrenheit degree.

History: The Rankine scale was developed for thermodynamic calculations in systems based on Fahrenheit.

Current use: Rankine appears in some engineering, thermodynamics, and legacy US customary calculations.

Also written as deg R.

The Celsius scale places water freezing at 0 and boiling at 100 under standard atmospheric pressure.

History: The scale evolved from the work of Anders Celsius and later refinements.

Current use: Celsius is the default temperature scale for weather and daily life in most countries.

Also written as deg C, °C, C, degC, degree C, degrees C, degree Celsius, degrees Celsius, centigrade.
