—Juan Perez, Dayton, Ohio Because Fahrenheit is so useful for everyday life. It wasn’t designed for that purpose, but on a human comfort scale of 1 to 100, it makes sense intuitively. We know 0°F is extremely cold for us and 100°F is extremely hot. And between those poles, Fahrenheit has 100 gradations for better description. But Celsius? That same “extremely cold” is about -18°C, and “extremely hot” is about 38°C. Familiarity with the range doesn’t help in a meaningful way. I vote for Celsius to stay in the sciences, where it makes more sense.
