Area measures two-dimensional surface size. The SI unit is the square meter (m²); common related units include the square kilometer (km²), hectare (ha = 10,000 m²) for land, square inch and square foot for indoor space, and the acre (4,046.86 m²) for property. 1 acre equals 43,560 ft²; 1 hectare equals 2.47105 acres.

Metric area units
The square meter is the SI base for area. For larger surfaces, the hectare (10,000 m², or a 100 m × 100 m square) is the practical unit, used for land in most metric countries. The square kilometer (1,000,000 m²) appears in geography, country sizes, and large-scale planning. For small surfaces, the square centimeter (cm²) and square millimeter (mm²) cover most lab, manufacturing, and electronics work.
Decimal prefixes apply consistently, but watch the squaring: 1 m² is 10,000 cm² (not 100 cm²), because the conversion factor between meters and centimeters (×100) gets squared when applied to area. Many off-by-100 unit mistakes trace to forgetting to square the prefix factor.
US customary and imperial area units
Square feet and square inches handle most everyday US measurements. A 1,500 sq ft home, a 100 sq ft room, a 12 in × 12 in tile. The acre, defined as 43,560 square feet (or 1 chain × 1 furlong in older surveys), is the standard land unit in the US, UK, and several Commonwealth countries.
Square yards (9 ft² each) show up in carpet and fabric. Square miles (640 acres, or 2.59 km²) appear in geography and US county-scale measurements. The hectare is starting to appear in US real estate listings that reference international comparisons but isn't a native customary unit.
Conversion practicalities
1 m² is 10.7639 ft². 1 ft² is 0.0929 m². For quick estimates, multiply square meters by 10 to get a rough square-foot figure (off by ~7%). 1 acre is roughly 0.4 hectares; 1 hectare is roughly 2.5 acres. 1 square mile is 640 acres exactly, a tidy ratio that survives from the US Public Land Survey System.
For carpet or flooring calculations, always include 10-15% waste for cuts and pattern matching. For paint coverage, square footage from interior wall area determines gallons needed, typically with one gallon covering 350-400 sq ft.

Frequently asked questions
How many acres is 1 hectare?
1 hectare is 2.47105 acres.
Why is 1 acre such an odd number (43,560 ft²)?
It's a historical unit from medieval English agriculture: 1 acre was originally the area a yoke of oxen could plow in a day, conventionally a 1-furlong (660 ft) by 1-chain (66 ft) strip. 660 × 66 = 43,560 ft². The shape varied, but the area definition stuck.
How big is a hectare in everyday terms?
1 hectare is a 100 m × 100 m square, about the size of an international football pitch (a FIFA-regulation field is ~0.7 ha). A typical suburban quarter-acre US lot is about 0.1 hectares.
Why does my unit conversion show different numbers for 'square feet'?
Make sure you're squaring the linear conversion. 1 m = 3.2808 ft, but 1 m² = 10.7639 ft² (not 3.2808). A common mistake is forgetting to square the prefix factor when converting area units.
