What is 40 degrees Celsius in Fahrenheit?

• A. 103 degrees Fahrenheit
• B. 104 degrees Fahrenheit
• C. 100 degrees Fahrenheit
• D. 105 degrees Fahrenheit

Answer: (B)

Converting Celsius to Fahrenheit uses the relationship F = (C × 9/5) + 32. For 40°C, multiply by 9/5 (which is 1.8): 40 × 1.8 = 72. Then add 32 to account for the offset between the scales: 72 + 32 = 104. So 40 degrees Celsius equals 104 degrees Fahrenheit. This aligns with the standard points that 0°C equals 32°F and that each degree increase in Celsius corresponds to a 1.8-degree increase in Fahrenheit. The other numbers arise from misapplying the conversion or missing the +32 offset.
