What is the Fahrenheit equivalent of 38 C at the threshold?

• A. 98.6 F
• B. 100.4 F
• C. 101.3 F
• D. 102.2 F

Answer: (B)

The key idea is converting Celsius to Fahrenheit with F = C × 9/5 + 32. For 38 °C, multiply by 9/5 (which is 1.8): 38 × 1.8 = 68.4. Then add 32 to get 100.4 °F. So 38 °C equals 100.4 °F. In clinical terms, 38 °C is a fever threshold, so 100.4 °F reflects fever. The other values correspond to different Celsius temps: 98.6 °F is normal body temperature (37 °C), about 101.3 °F is roughly 38.5 °C, and 102.2 °F is about 39 °C.
