How to Convert Delisle to Réaumur

Formula:

°Re=(100−(°De×23))×45°\text{R}e = \left(100 - \left(°De \times \frac{2}{3}\right)\right) \times \frac{4}{5}

Example

Convert 15 °De to °Re:

°Re=(100−(°De×23))×45°\text{R}e = \left(100 - \left(°De \times \frac{2}{3}\right)\right) \times \frac{4}{5}
°Re=(100−(15×23))×45°\text{R}e = \left(100 - \left(15 \times \frac{2}{3}\right)\right) \times \frac{4}{5}
°Re=72°\text{R}e = 72
=72 °Re= 72 \, °\text{R}e
