About Square Mile (mi²)
An imperial unit of area equal to approximately 2.589988 km² (= 640 acres = 27,878,400 ft² exactly per NIST SP 811). Square miles are the customary US unit for: US county sizes per US Census Bureau (San Bernardino County, CA at 20,105 mi² is largest US county outside Alaska; Yukon-Koyukuk Census Area, AK is 145,505 mi²); US national parks (Wrangell-St. Elias National Park 13,005 mi² largest; Yellowstone 3,468 mi²; Yosemite 1,189 mi²; Grand Canyon 1,902 mi²; Death Valley 5,270 mi²); US metro-area footprints (Greater New York metro area ~13,318 mi²; Greater Los Angeles 4,850 mi²); US state sizes (Alaska 665,384 mi² largest; Rhode Island 1,545 mi² smallest); wildfire burn areas in US news reporting (2018 Camp Fire 240 mi²; 2020 California August Complex Fire 1,032 mi²; 2024 Park Fire 670 mi²); US watershed reporting per USGS HUC-12 boundary-area data. Geographic conversions between mi² and km² (multiply by 2.589988) are routine for US news consumers reading international reports and US federal-agency reports issued in dual units.
About Square Meter (m²)
The SI derived unit of area per ISO 80000-3 §3-3, equal to the area of a square with sides of exactly one meter (1 m² = 10,000 cm² = 10.764 ft²). Square meters are the global standard for: floor-plan area on architectural drawings per ISO 7518 + ISO 9836, real-estate listings outside the US (RICS Code of Measuring Practice for UK, IPMS — International Property Measurement Standards globally, REIQ for Australia), room measurements per IBC / Eurocode building codes (minimum 7 m² bedroom, 4.5 m² kitchen per typical residential housing codes), and every SI-derived areal quantity including pressure (1 Pa = 1 N/m²), surface tension (N/m), heat flux (W/m²), magnetic flux density (1 T = 1 Wb/m²), and luminance (cd/m²). Reference areas: typical hotel room ~25 m²; standard US two-car garage ~37 m²; basketball court 420 m² (NBA full court 28 × 15 m); ISO 20 ft shipping container floor 14.4 m²; ISO 40 ft container 29 m²; FIFA-regulation soccer pitch 7,140 m² (105 × 68 m); American football field excluding end zones 4,415 m²; the area of one square nautical mile is 3,429,904 m².
