What is the boiling temperature of water in Fahrenheit and Celsius?

• A. 32 F 0 C
• B. 100 F 37 C
• C. 212 F 100 C
• D. 180 F 82 C

Answer: (C)

Boiling point under standard atmospheric pressure is where water shifts from liquid to vapor. That occurs at 100 C, which equals 212 F. So the pairing of 212 F and 100 C is the correct one. The other numbers correspond to other reference points: 32 F is the freezing point (0 C); 37 C is normal body temperature; 180 F is not the boiling point at standard pressure and doesn’t line up with a standard Celsius value for boiling. This shows how Celsius and Fahrenheit map to key phase-change temperatures.
