About Area conversions
Area conversions matter in real estate, agriculture, construction, and mapping. Square footage (sq ft) dominates US real estate listings, while the rest of the world uses square meters (m²). This trips up international buyers comparing property sizes: 100 m² equals 1,076 sq ft — so a "1,000 sq ft apartment" in the US is just 92.9 m², which sounds small in European terms.
In agriculture, US farmers use acres while international farming uses hectares. 1 hectare = 2.471 acres = 10,000 square meters. A standard American football field including end zones is about 0.537 hectares (1.32 acres). For very large areas like national parks or countries, the units switch to square miles or square kilometers — 1 square mile = 2.59 km².
For home improvement, knowing area conversions helps estimate paint, flooring, and tile coverage. Paint typically covers 350–400 sq ft per gallon (33–37 m² per 3.79 L). Flooring specs may list coverage in either system depending on where the product is manufactured.
