Area Converter Guide
Metric / Chinese / Imperial
The area converter covers 13 units across the metric, imperial and Chinese systems for land surveying, real estate appraisal, interior design, agricultural planning, floor-area calculations and cross-border property comparison. Area units have a square relationship, so the conversion factor is the square of the length factor. The tool is based on the square meter; enter any area value to instantly get every equivalent unit, including the Chinese mu and the imperial acre and square foot.
01 Unit systems
Metric is based on the square meter (m²): 1 hectare (ha) = 10,000 m² = 0.01 km², 1 are (a) = 100 m², 1 square kilometer = 1,000,000 m². In imperial, 1 square foot ≈ 0.0929 m², 1 square yard ≈ 0.836 m², 1 acre (ac) = 4046.856 m² ≈ 0.4047 ha, 1 square mile ≈ 2.59 km². The acre is widely used for large land parcels in the US and UK.
The mu (市亩) is a traditional Chinese land unit: 1 mu ≈ 666.67 m² = 1/15 hectare, and 1 hectare = 15 mu. It remains common in rural land transfer, agriculture and land-use assessment. The key principle is that area is a square quantity: since 1 m = 100 cm, 1 m² = 10,000 cm².
- 1 ha = 10,000 m² = 15 mu ≈ 2.471 ac
- 1 mu ≈ 666.67 m² = 1/15 ha
- 1 ac ≈ 4046.86 m² ≈ 6.07 mu
- 1 ft² ≈ 0.0929 m²
- 1 mi² ≈ 2.59 km²
02 How to use
Enter an area value and choose the source unit (e.g. square meters); the right instantly shows the target (e.g. mu or square feet), and the all-units overview lists every area unit. Property area is usually quoted in square meters or square feet, while land uses mu, hectares or acres — choose the unit appropriate to your scenario.

FinCompute’s free online area converter covers 13 units across metric, imperial and Chinese systems. Whether you need mu to square meters for land area, square feet to square meters for home buying, or hectares to mu for farmland, enter any area to see all units at once.
Metric area: square millimeters to square kilometers, ares and hectares
1 hectare = 10,000 m², 1 km² = 1,000,000 m², 1 are = 100 m². Area is the square of length, so conversion factors are squared: 1 m = 3.28 ft means 1 m² = 10.76 ft², not 3.28 ft².
Imperial area: acres and square feet for home buying and overseas property
1 acre = 43,560 ft² = 4,840 yd² ≈ 4,046.86 m², 1 ft² ≈ 0.0929 m², 1 mi² ≈ 2.59 km², widely used in the US, UK and former British territories for land and property. Compare ft² vs m² home prices or overseas acreage instantly.
Chinese area: mu — standard for farmland and land transactions
1 mu ≈ 666.67 m² = 1/15 hectare, and 1 hectare = 15 mu (exactly). The mu is a traditional Chinese unit still widely used in agriculture, land transactions and government land statistics — "how many m² in a mu of land" and "how many mu in a hectare" are common queries.
Common area conversions: real estate, land, interior design and agriculture
Homebuyers compare properties listed in m² (China/Europe) and ft² (US/UK); farmers calculate field sizes in mu or acres; interior designers convert room dimensions for paint and flooring; real estate agents price per m² or per ft²; architects work with hectares for site planning; logistics staff calculate warehouse floor area.
Area conversion formulas: international acre exactly 4,046.8564224 m²
Square feet to m²: m² = ft² × 0.092903. Acres to m²: m² = acres × 4046.856. Hectares to acres: acres = hectares × 2.47105. Mu to m²: m² = mu × 666.667. The international acre is defined as exactly 4,046.8564224 m², based on the 1959 international yard.

FAQ
QHow many m² in a mu?
1 mu ≈ 666.67 m², i.e. 1⁄15 hectare. This is the mainland China standard established in 1929.
QHow many mu in an acre?
1 acre ≈ 4,046.86 m² ≈ 6.07 mu. Conversely, 1 mu ≈ 0.1647 acres.
QHow many mu in a hectare?
1 hectare = 10,000 m² = 15 mu exactly.
QHow many m² in a square foot?
1 ft² = 0.092903 m². To convert ft² to m², multiply by 0.0929.
QWhich unit is used for property?
Chinese and European property is priced per m²; US/UK property per ft². Use this converter to compare listing prices across countries.
QWhy might two sources show slightly different acre conversions?
The US still uses a "survey acre" in some land records, based on the pre-1959 survey foot. It differs from the international acre by about 0.016 m² (0.0004%). Modern documents use the international standard, which this converter applies.
QHow big is an acre visually?
An acre is roughly 90% of a US football field (without end zones), or about ⅔ of a soccer pitch. It equals a square of roughly 63.6 meters (208.7 feet) per side.
QHow many square meters is a mu of land?
1 mu ≈ 666.67 m² = 1/15 hectare. This is the mainland China standard used for farmland and land transfers; 1 hectare = 15 mu exactly.
QHow do I convert square feet to square meters when buying a home?
1 ft² = 0.092903 m². For example a 1,000 ft² apartment is about 92.9 m². Enter the square-foot value to see m², mu, acres and all other units at once.
QHow many mu are in a hectare?
Exactly 15. 1 hectare = 10,000 m² = 15 mu ≈ 2.471 acres. This makes it easy to compare Chinese farm-subsidy areas with international acreage figures.
QHow many acres are in a square kilometer?
1 km² = 100 hectares ≈ 247.1 acres ≈ 0.386 square miles. Use the converter to check city or national-park areas across any unit.
QHow many square meters is a 100 square foot room?
1 ft² = 0.0929 m², so 100 ft² ≈ 9.29 m². For a quick mental estimate, divide square feet by 10; for an exact figure use the converter.
QHow many mu in 10,000 square meters of farmland?
1 hectare (10,000 m²) = 15 mu exactly, so the answer is 15 mu. This makes Chinese farm-subsidy and land-transfer calculations straightforward: divide m² by 666.67 to get mu, or multiply hectares by 15.
