How to Convert Fahrenheit to Réaumur

Formula:

°Re=(°F−32)×49°\text{R}e = \left(°\text{F} - 32\right) \times \frac{4}{9}

Inverse formula:

°F=°Re×94+32°\text{F} = °\text{R}e \times \frac{9}{4} + 32

Example

Convert 15 °F to °Re:

°Re=(°F−32)×49°\text{R}e = \left(°\text{F} - 32\right) \times \frac{4}{9}
°Re=(°F−32)×49°\text{R}e = \left(°\text{F} - 32\right) \times \frac{4}{9}
°Re=−7.55556°\text{R}e = -7.55556
=−7.55556 °Re= -7.55556 \, °\text{R}e
