Which formula converts Fahrenheit to Celsius as listed in the material?

• A. F = 9/5 (C+32)
• B. F = (C - 32) × 9/5
• C. C = 9/5 (F+32)
• D. C = (F - 32) × 5/9

Answer: (D)

Converting Fahrenheit to Celsius uses a linear relationship that accounts for the different zero points and the size of each degree. The correct formula subtracts 32 to align with the Celsius zero, then multiplies by 5/9 to convert the Fahrenheit degree size to Celsius degrees. So you get C = (F − 32) × 5/9. This is just a rearrangement of F = (9/5)C + 32 solved for C. For example, 68°F → C = (68 − 32) × 5/9 = 36 × 5/9 ≈ 20°C. 212°F → C = (212 − 32) × 5/9 = 180 × 5/9 = 100°C. 0°F → C ≈ (0 − 32) × 5/9 ≈ −17.8°C. Other forms mix up the offset or the direction of the conversion, so they don’t correctly map Fahrenheit temperatures to Celsius temperatures.
