Evenly distributing 98 markings is hard. Evenly distributing 64 is easy -- just halve the range six times. That's why the distance from freezing water to body temperature is 64 Fahrenheit degrees.
- Schweigi 12y agoI don't think its advisable to use my self-made quicksilver thermometer for any kind of body temperature measurement.
- XorNot 12y agoWhich makes no difference because you're eyeballing it to start with. You can just as easily divide the 0-100 range in half a bunch of times. Your thermometer is not achieving <1 degree accuracy. Of course if you have a tool to accurately measure halves, then you can also measure any other division you care to use.
- BlackAura 12y agoExcept... 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.
