How to Convert Delisle to Celsius

Formula:

°C=100−(°De×23)°\text{C} = 100 - \left(°De \times \frac{2}{3}\right)

Example

Convert 15 °De to °C:

°C=100−(°De×23)°\text{C} = 100 - \left(°De \times \frac{2}{3}\right)
°C=100−(15×23)°\text{C} = 100 - \left(15 \times \frac{2}{3}\right)
°C=90°\text{C} = 90
=90 °C= 90 \, °\text{C}
