Rankine To Romer (°R To °Rø) Converter

The Rankine to Rømer (°R to °Rø) Converter is a simple tool designed to help you easily convert temperatures from the Rankine scale to the Rømer scale. Both scales are used to measure temperature, but they differ in their reference points and increments.

The Rankine scale (°R) is an absolute temperature scale used mainly in engineering, especially in the United States. It starts at absolute zero, which is 0°R, equivalent to -459.67°F. Each degree Rankine is equal to one degree Fahrenheit, so the scale increases linearly from absolute zero.

The Rømer scale (°Rø) is an older temperature scale invented by Daniel Gabriel Fahrenheit’s student, Ole Rømer. It is based on the freezing point of brine and water, with 0°Rø set at the freezing point of brine. The scale is less common today but still useful for historical or scientific purposes.

To convert from Rankine to Rømer, you can use the following formula:
°Rø = (°R – 491.67) × 0.525 + 7.5

In this formula, subtract 491.67 from the Rankine temperature to convert it to Fahrenheit, then multiply by 0.525 to convert Fahrenheit to Rømer, and finally add 7.5 to align with the Rømer scale’s zero point. This converter automates the calculation, making it easy for you to switch between these two temperature units accurately.
