When you'd convert degrees Fahrenheit to degrees Celsius
Use it for US recipes and weather: 350 °F is about 177 °C, a common oven setting.
Rough shortcut: subtract 30 and halve.
Common mistake: temperature scales have different zero points, so you cannot just multiply; a change of 1 °C is a change of 1.8 °F, but 1 °C is not 1.8 °F.
To go the other way, use the degrees Celsius to degrees Fahrenheit converter.
