Celsius vs Fahrenheit Thermometers: Temperature Turf War

In Stockholm, 1742, Anders Celsius set freezing water at zero and boiling at one hundred on his brand new thermometer. Meanwhile, over in Germany, Gabriel Fahrenheit’s 1724 scale marked freezing at thirty-two and boiling at two hundred twelve. On a Celsius thermometer, every jump from zero to one hundred measures the common freezing to boiling points of water. But look at Fahrenheit, and that same water turns into thirty-two at freezing, with a much bigger gap up to two hundred twelve at boiling. Celsius uses metres-everything divides into tens and hundreds. Fahrenheit stretches things out, making small temperature changes stand out more in daily weather. Imagine you see twenty degrees on both: in Celsius, it’s cool spring; in Fahrenheit, that’s shivering winter. Remember this: zero Celsius means ice, but zero Fahrenheit means really, really cold air in old Danzig. Stockholm’s scale for scientists, Germany’s for weather-watchers. Celsius and Fahrenheit: two ways to read our world’s heat-never the same number, but always measuring the same truth.
