Quick answer
To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9: °C = (°F − 32) ÷ 1.8. So 350°F, a common baking temperature, is 177°C, and 98.6°F (body temperature) is 37°C.

How to convert F to C
Baking is where this conversion causes the most everyday friction: a US recipe calling for "350°F" needs an oven set to 177°C, but ovens outside the US are typically marked in round numbers (175°C or 180°C), so a home cook converting by hand has to decide whether to round up or down, and either choice shifts the actual bake slightly from what the recipe author tested.
The subtraction has to happen before the multiplication, not after: (°F − 32) × 5/9, never °F × 5/9 − 32, because the offset belongs to the Fahrenheit scale's zero point, not the Celsius one. Doing the steps in the wrong order gives a answer that is close enough to look plausible but is measurably wrong.
