Why do we measure angles, distances, and weight differently?

You've probably noticed something weird. We slice pizza into degrees, measure rooms in feet or meters, and weigh apples in pounds or kilograms. Why don't we use one system for everything? Why does the world have so many different measuring sticks?
Here's the thing: angles, distances, and weights are measuring completely different kinds of stuff. An angle measures how far something has turned or opened — like the hands of a clock spinning, or your mouth opening wide for a dentist. There's no length to grab, no heaviness to lift. You're measuring rotation, pure and simple.
