Rømer to Fahrenheit Conversion: A Comprehensive Guide

The Rømer and Fahrenheit scales are both historical temperature scales. While Fahrenheit remains in use today, understanding the conversion between them can be valuable for historical research or scientific data analysis. This guide will walk you through the conversion process and provide a convenient online calculator.

Understanding the Rømer Scale

Developed by Danish astronomer Ole Rømer in 1701, the Rømer scale is a descending scale. It defines the freezing point of brine (a mixture of salt and water) as 0°Rø and the boiling point of water as 60°Rø.

Understanding the Fahrenheit Scale

Invented by German physicist Daniel Gabriel Fahrenheit in 1724, the Fahrenheit scale is widely used, particularly in the United States. On this scale, the freezing point of water is 32F, and the boiling point of water is 212°F.

The Conversion Formula

To convert Rømer to Fahrenheit, use the following formula:

**Fahrenheit (°F) = (Rømer (°Rø) * (21/40)) + 32**
