"""And exactly how often do you need to measure the temperature when water boils?""" I drink green tea a lot. You pour the water at 70-75 degrees C. It's a lot easier to do the math of how much water you need to add to instantly cool the water from the water boiler down to that range. """Labs and Ovens don't really care about which exact unit, so let them deal with the higher (or lower) numbers - the only time it matters is for ordinary humans checking the weather.""" What? I use temperature more when cooking/BBQing than when checking the weather. """With Celsius you need to deal with negative temperatures all the time""" This is a feature, not a bug. Negative number -> below freezing. """0 Fahrenheit is the temperature when it's really cold outside, 100 is when it's hot. It doesn't get simpler than that. If you are outside those ranges you need to take special precautions.""" I also need to take special precautions within these ranges. Most notably switching between summer/winter tires.
