Why do we measure things in different units around the world?
You've probably noticed that sometimes your friend's height is in feet and inches, but on a doctor's chart it's in centimeters. A recipe calls for cups, but the milk carton shows liters. Your weather app says 75°F while your cousin in another country sees 24°C. Why can't everyone just agree?
The answer goes back thousands of years, to a time before rulers or scales existed. People still needed to measure things — how much grain to trade, how far to the next village, how long to build a fence. So they used what they had: their own bodies.
