Delisle to Rankine: A Comprehensive Guide

Delisle and Rankine are temperature scales used in various scientific and engineering fields. This guide will help you understand how to convert between these two scales, along with providing a convenient online calculator.

Delisle Scale: An Overview

The Delisle scale, developed by French astronomer Joseph-Nicolas Delisle in 1732, is a descending scale. It defines the boiling point of water as 0°D and the freezing point of water as 150°D.

Rankine Scale: An Absolute Temperature Scale

The Rankine scale, named after Scottish engineer William John Macquorn Rankine, is an absolute temperature scale. It's based on the Fahrenheit degree but with absolute zero as its starting point, resulting in no negative temperatures.

Delisle to Rankine Conversion: The Formula

The conversion from Delisle to Rankine can be calculated using the following formula:

Rankine (°R) = [(491.67 - (Delisle (D) * (9/5))] * 5/9 + 491.67
