Which equation correctly converts Fahrenheit to Celsius?

Converting Fahrenheit to Celsius starts by removing the 32-degree offset, then scaling the result by 5/9 because Fahrenheit degrees are larger than Celsius degrees. The correct form is C = (F − 32) × 5/9. This works because the freezing point of water is 0°C and 32°F, so you first align the zero points, then adjust for the size of each degree. For example, F = 212 gives C = (212 − 32) × 5/9 = 100, which matches the boiling point of water in Celsius. The other expressions either describe the inverse relation (F in terms of C, not C in terms of F) or use ambiguous notation that can be misread, leading to the wrong result.
