His name was Daniel Gabriel Fahrenheit. A German-Polish-Dutch guy with a thing for thermometers. He was the original gadget nerd.
He didn’t just pick 32 out of a hat, though it kind of seems like it. He built his scale in the early 1700s.
Here’s where it gets playful. He wanted a scale that didn’t use negative numbers for everyday weather. Can you blame him? Negatives are depressing.
What’s So Special About 32?
Fahrenheit famously used a mixture of ice, water, and ammonium chloride (a kind of salt). That concoction created the lowest temperature he could reliably make in his lab.
He called that point 0°F. Brrr. Think of it as his “I’m freezing my lab coat off” benchmark.
Then, he stuck a thermometer in his mouth (or under his armpit—historians aren’t sure). He marked that as 96°F. Because the human body felt nice and stable.
