Except... Freezing point of water: 32°F
Average human body temperature (oral): 98.2°F So that's 66.2°F, not 64°F. Those two temperatures were the original reference points for the Fahrenheit scale, and body temperature was defined as 96°. The current definition is relative to the melting point of ice (32°F), and the boiling point of water at standard atmospheric pressure (212°F, which is exactly 180°F higher than the freezing point). Except now body temperature is 98.2°F instead of 96°. If you want a thermometer calibrated in Fahrenheit, you have exactly the same problem as you do with Celsius. You just have to put 178 markings between the two reference points, rather than 98. |
