India-Specific Land Units

In India, land is often measured in local units. While this converter uses international standards, here are common Indian equivalents:

1 Bigha = varies by state (1,500—6,800 ft—)
1 Guntha = 1,089 ft— (Maharashtra)
1 Ground = 2,400 ft— (Tamil Nadu)
1 Cent = 435.6 ft— (Kerala)

Frequently Asked Questions

1 square meter equals 10.7639 square feet. To convert sq meters to sq feet, multiply by 10.7639. For a quick estimate, multiply by 11.

1 hectare equals 2.47105 acres. A hectare is a metric unit equal to 10,000 square meters (100m — 100m). It's commonly used for measuring land area in most countries outside the US.

An acre is an imperial unit (4,046.86 m— or 43,560 ft—). A hectare is a metric unit (10,000 m—). A hectare is about 2.47 times larger than an acre. Acres are used in the US and UK; hectares are used in most other countries.

Area units across the world

Area is one of the most fragmented unit families because so many regional systems remain in everyday use. The metric base is the square metre, but agricultural land is typically traded in hectares (1 ha = 10,000 m²), house plots in many South Asian markets are sized in square feet alongside local units like the Indian gaj, marla, kanal, bigha, and katha, while US real estate uses square feet and acres (1 acre = 43,560 ft²).

Conversion anchors worth memorising

1 m² = 10.7639 ft²
1 acre = 4046.8564 m² = 0.4047 ha
1 hectare = 2.4711 acres
1 square mile = 640 acres = 2.59 km²
1 square yard = 9 ft² = 0.8361 m²

When small differences matter

Real-estate sizing is one place where rounding errors translate directly to money. A 1200 ft² apartment is 111.48 m², not 111.5 m² — the difference is enough to nudge property tax brackets in some jurisdictions. Carpet, flooring, and paint estimates work the other way: rounding up by 5–10% is normal to allow for waste.

Practical use cases

Solar installers commonly think in W per square metre of usable roof. Farmers think in yield per hectare or per acre. Civil engineers detail in square metres for slabs and in square feet for finishes when working with US-standard contracts.
