よくある質問
How do I calculate the square footage of a room?
Multiply length by width in feet, or use the square footage calculator for several rooms and shapes.
Why isn't 1 m² = 3.28 ft²?
Because area scales with the square: 1 m = 3.2808 ft, so 1 m² = 3.2808² ≈ 10.764 ft².
How big is an acre?
About 4,047 m², roughly 75% of an American football field including end zones.
