What is the formula to convert Fahrenheit to Celsius?

To convert Fahrenheit to Celsius, you remove the 32-degree offset and scale by 1.8. This comes from starting with F = C × 1.8 + 32 and solving for C, which gives C = (F − 32) ÷ 1.8 (or C = (F − 32) × 5/9). So you subtract 32 from the Fahrenheit temperature, then divide by 1.8. For example, 68°F → (68 − 32)/1.8 ≈ 20°C, and 212°F → (212 − 32)/1.8 = 100°C. This also confirms the lower point: 32°F is 0°C. The other forms mix up the operations or swap the roles of Fahrenheit and Celsius, so they don’t yield correct values in general.
