Fahrenheit to Celsius (°F to °C)
Temperature scales have different zero points as well as different degree sizes, so there is no single multiplier. Subtract 32 from the Fahrenheit reading, then multiply by 5/9.
Formula
°C = (°F − 32) × 5 ÷ 9
Example: 50 degrees Fahrenheit = 10 degrees Celsius.

Good to know
Weather: a quick estimate is to subtract 30 and halve. 80 °F − 30 = 50, ÷ 2 = 25 °C (exact: 26.7). The estimate drifts at extremes, so use the exact figure for anything that matters.
Cooking: 350 °F is 177 °C, usually rounded to 180 °C on European recipes; 400 °F is 204 °C (200 °C). Fan ovens are typically set about 20 °C lower than conventional ones — check your oven's manual.
Body temperature: 98.6 °F is 37 °C. A fever is commonly defined as 100.4 °F (38 °C) or higher.
