How to Convert Delisle to Rankines

Formula:

°R=(100−(°De×23))×95+491.67°\text{R} = \left(100 - \left(°De \times \frac{2}{3}\right)\right) \times \frac{9}{5} + 491.67

Example

Convert 15 °De to °R:

°R=(100−(°De×23))×95+491.67°\text{R} = \left(100 - \left(°De \times \frac{2}{3}\right)\right) \times \frac{9}{5} + 491.67
°R=(100−(15×23))×95+491.67°\text{R} = \left(100 - \left(15 \times \frac{2}{3}\right)\right) \times \frac{9}{5} + 491.67
°R=653.67°\text{R} = 653.67
=653.67 °R= 653.67 \, °\text{R}
