About Square Kilometer (km²)
A metric unit of area equal to exactly 1,000,000 m² (a square with 1-kilometer sides). Square kilometers are the default unit for geographic scale: country sizes per CIA World Factbook + UN Statistics Division (Russia 17,098,242 km² largest; Vatican City 0.49 km² smallest; USA 9,833,517 km²; China 9,596,961 km²; Brazil 8,515,767 km²; Australia 7,692,024 km²; Canada 9,984,670 km²; France 643,801 km²; UK 243,610 km²; Germany 357,022 km²; Japan 377,975 km²); city/metro footprints (Manhattan 59 km²; NYC 783.8 km²; London Greater 1,572 km²; Tokyo 23 special wards 627 km²; Mexico City 1,485 km²); forest and agricultural land per FAO FRA reporting; deforestation tracking per MapBiomas, Global Forest Watch (Amazon biome ~5.5 million km²); urban heat-island and wildfire burn-area reporting in news (2018 Camp Fire 620 km²; 2020 Australian bushfires 186,000 km²); lake and watershed areas (Lake Superior 82,100 km²; Mississippi River basin 3,202,200 km²); satellite-imagery scene footprints (Landsat 8 scene ~32,000 km²). km² is the preferred unit in most international geographic statistics, climate models, and macro-scale GIS analysis.
About Square Foot (ft²)
An imperial unit of area equal to exactly 0.09290304 m² per NIST SP 811 — a square with 1-foot sides. Square feet are the dominant unit for: US residential and commercial real-estate listings (NAR — National Association of Realtors — and Zillow listings always quote 'sqft' or 'square feet'; a typical US new single-family home 2,261 ft² per US Census Bureau 2024 data; condominium and townhouse units 800-2,000 ft²); commercial office and retail leases (CBRE / JLL / Cushman & Wakefield rent rates quoted per ft²/yr; typical Class-A office 30-100 USD/ft²/yr; retail anchor space 15-40 USD/ft²/yr); paint coverage calculations (1 gallon of latex paint covers ~350-400 ft² per Sherwin-Williams / Behr / Benjamin Moore product data); flooring estimates (carpet, hardwood, LVT, ceramic tile, vinyl plank pricing quoted per ft²); landscaping bids and lawn-treatment service rates; HVAC capacity sizing per ACCA Manual J (one ton of cooling for ~500-700 ft² in moderate US climates). US-edition building codes (IBC, IRC) and IBC accessibility (ANSI A117.1) specify minimum areas in ft².
