From rooms to farmland
Area is length multiplied by length, so each unit is the square of a distance. That is why the numbers grow quickly: a square meter is far more than a square centimeter, because both sides have stretched by a hundred.
Two land units do the heavy lifting in real estate and agriculture. The acre, an old measure once tied to a day's plowing, still appears on property listings in the United States. The hectare, equal to 10,000 square meters, is the metric standard for land and sits at about two and a half acres.
