Square meter converter — m² to ft², acre, hectare, are
The square meter converter takes any m² value and converts it to square feet, square yards, square inches, square centimeters, square millimeters, square kilometers, acres, hectares, and ares. All factors derive from SI definitions and the 1959 international yard treaty. 1 m² equals 10.7639 sq ft, 1.196 sq yd, 10 000 cm², or 0.0001 hectare.
The square metre is the SI derived unit of area, defined directly from the SI metre. Since the metre is defined by the speed of light, every other area unit ultimately traces to a defining physical constant. This means a square meter converter using exact factors has zero measurement uncertainty — the conversion is as precise as the input data.
What is the square meter converter?
A square meter converter routes every area value through m² as a pivot. To convert sq ft to acres, the tool computes sq ft → m² → acres. Internally, each unit has one factor (its size in m²); the conversion is just division by the destination factor after multiplying by the source factor.
The converter on this page handles 10 area units. Imperial units (sq ft, sq yd, sq in, acre) use 1959 treaty factors. Metric units (cm², mm², km², hectare, are) are exact decimal multiples of m². The square kilometre is one million m². The hectare is ten thousand m². The are is one hundred m². Each step is a clean factor of 100, reflecting the underlying linear factor of 10.
Square meter conversion factors
- 1 m² → cm² = 10 000 (100² because 1 m = 100 cm)
- 1 m² → mm² = 1 000 000
- 1 m² → km² = 0.000001 (1 km² = 1 million m²)
- 1 m² → sq ft = 10.7639
- 1 m² → sq yd = 1.19599
- 1 m² → acre = 0.000247
- 1 m² → hectare = 0.0001
- 1 m² → are = 0.01
Square meter to square feet
The m² to sq ft conversion is the most-used path in the square meter converter, especially for international real-estate comparisons. 1 m² = 10.7639 sq ft. A 60 m² European apartment is 646 sq ft. A 200 m² family home is 2153 sq ft — comparable to a US suburban median. The exact factor 10.76391041671 is the reciprocal of 0.09290304 (1 sq ft in m²).

Most of the world uses square metres exclusively. The notable hold-outs are the US (sq ft everywhere), the UK (sq ft in real estate, m² in science and EU-aligned documents), and parts of South Asia (where local units like gaj, katha, bigha, and marla persist alongside m²).
India's traditional unit gaj equals exactly 1 square yard = 0.8361 m². Property listings in Delhi and Mumbai often mix m², sq ft, and gaj in the same description. A 50 gaj plot is 50 sq yd = 41.8 m² = 450 sq ft.

Apartment sizes by country (median listing data):
European median apartments cluster around 70-90 m². US apartments are larger, with a 1-bed median near 70 m² (754 sq ft). Australian and Canadian homes top the chart with detached median sizes of 189 m² and 166 m² respectively. The square meter converter makes these cross-country numbers directly comparable.
Square meter in agriculture and surveying
Agricultural land uses larger metric units. The hectare (1 ha = 10 000 m²) is the EU standard. The are (1 a = 100 m²) is still in legal use for cadastral records in Poland, Germany, France, Switzerland, and the Czech Republic. A typical EU farm might be measured in hectares — 50 ha = 500 000 m² = 123.6 acres = 0.5 km².
Surveying-grade GPS gives accuracies of 1-2 cm, far below the square meter level. The square meter converter is precise to whatever decimal you display, but real-world land-area measurements rarely warrant more than 2 decimals — a 1234.56 m² plot might be ±0.5 m² depending on boundary marker conditions.
Square meter converter mistakes to avoid
Linear vs area factor: 1 m = 100 cm (linear factor 100), but 1 m² = 10 000 cm² (area factor 100² = 10 000). Squaring is mandatory.
Confusing acre with are: 1 acre = 4047 m², 1 are = 100 m². They look similar but differ by a factor of 40.
Forgetting precision: 1 m² to sq ft using "10" gives a 7% error. Using "10.76" gives 0.04% error. Use the full factor 10.7639 (or the exact reciprocal 0.09290304) for any contract or filing.
Square meter converter quick rules
Multiply m² by 10.76 to get sq ft. Divide by 10 000 to get hectares. Divide by 4047 to get acres. Multiply by 10 000 to get cm². For agricultural land, learn 1 hectare = 2.471 acres and 1 acre = 0.4047 hectare. For real estate, learn 1 m² = 10.76 sq ft and 100 m² ≈ 1076 sq ft. With those four numbers, you can sanity-check any square meter converter result mentally.
When comparing US and European housing listings, multiply the m² value by 10.76 first. A 75 m² apartment becomes 807 sq ft — close to a typical US 1-bedroom. Conversely, divide a US 2000 sq ft house by 10.76 to get 186 m² — a large family home by European standards.
For agricultural land, the natural unit is hectares: divide m² by 10 000. A 5 hectare field is 50 000 m². For a US-style ranch, multiply hectares by 2.471 to get acres. A 100-hectare farm equals 247 acres or about 0.39 square miles. The square meter converter handles all of these in one step, but the mental anchors are worth memorising.
Sub-metre area units are useful only in materials science and electronics. Square millimetres for PCB pad areas, square centimetres for textile or paint coverage, and square micrometres for semiconductor die layouts. Each step is a factor of 100 from m², so 1 mm² = 0.000 001 m², 1 cm² = 0.0001 m², 1 μm² = 10⁻¹² m². The square meter converter on this page rounds to the displayed precision but internally uses 64-bit floats, so there is no rounding loss across the 10-unit range.
