What the Fahrenheit?!

When winter looms, we start to pay more attention to the thermometer. The Fahrenheit thermometers in the U.S. are altogether confusing for folks in most of the rest of the world. Why does water freeze at 32°F instead of the more sensible 0°C? We usually just shrug and say it's always been that way, but that's not true. There's a real history behind the scale, even if don't know all of it. Veritasium brings us the story of Daniel Gabriel Fahrenheit, who made wildly popular thermometers in the 18th century, with animation by Marcello Ascani. (via Laughing Squid)
