Delisle To Reaumur (°De To °Ré) Converter

The Delisle to Reaumur (°De to °Ré) Converter is a simple tool designed to help you easily convert temperatures from the Delisle scale to the Reaumur scale. It is useful for students, scientists, or anyone working with historical or international temperature measurements.

The Delisle scale (°De) was created by Joseph-Nicolas Delisle and is primarily used in historical contexts. On this scale, water freezes at 0°De and boils at 150°De. The scale decreases as temperature increases, meaning higher temperatures have lower Delisle values.

The Reaumur scale (°Ré), developed by René Antoine Ferchault de Réaumur, is based on the freezing point of water at 0°Ré and the boiling point at 80°Ré. It is mainly used in some European countries and in certain scientific contexts.

To convert from Delisle to Reaumur, you can use the following formula:
°Ré = 4/5 × (150 – °De)

This formula subtracts the Delisle temperature from 150, then multiplies by 4/5 to get the equivalent Reaumur temperature. Simply input your Delisle temperature into the converter, and it will provide the corresponding Reaumur value instantly.
