## Comment Re:Celsius: It's for telling temperature (Score 5, Insightful)1233

Seems to me that everybody saying Fahrenheit makes more sense as a "human" scale because humans can live within 0-100 F are just looking for excuses to keep to an obsolete scale.

1. Although 100C is too hot for human life it's encountered every day by everybody: just boil some water for cooking.

2. Fahrenheit is not more descriptive because the "degrees are smaller". We just use decimal places to do the same in C. We are not limited to 25 or 26 degrees; there's infinite variation between these if you use the right side of the decimal point, although using just the half point is usually enough. This particular misconception comes from Imperial measure users, who have to rely on fractions. Yes, fractions are more precise but not as useful as the arbitrary precision approximation built into the metric system. In fact, fractions are so awkward to use that you end up limiting yourself to 1/32 of an inch for most uses (or even 1/16), which is much *less* precision than a 5th grader can get with a few digits after the decimal point.

3. It's like people who say feet are better than meters because you can divide easily a feet by 1,2,3,4,6 and 12. They don't know that this "advantage" quickly goes away when compared to conversion elegance of the metric system. Take one meter. Make a cube of that side, a cubic meter. Fill that with water near the sea level and you get a volume of 1 Liter of water. Which happens to have a mass of Kilogram. Push that to an acceleration of a meter per second per second, it will take 1 Newton to do that. Push any object against a 1 Newton of force and you need 1 Watt to do that. Which happens to be 1 Joule of energy per second. Once you're done, mark the temperature at which the water you've been using freezes and call that 0. Mark the temp at which it boils and call that 100. Divide that in 100ths and you have the Celsius scale. Now say the same thing in Imperial units and go back to how awesome it is that you can divide by 12...
