Jak działa ten kalkulator?
Convert any land area by multiplying by an exact conversion factor to square meters, then to your target unit. One acre = 4,046.856 m² = 0.4047 ha = 43,560 ft²; one hectare = 10,000 m² = 2.471 acres. The calculator handles acres, hectares, sq ft, sq m, sq km, sq miles, rai, cents, and marla.

How this is calculated
The calculator converts the input value to square meters using an exact conversion factor, then divides by the target unit's factor to produce each output. For example, one acre equals exactly 4,046.8564224 m² (derived from the international definition: 1 acre = 43,560 sq ft, 1 ft = 0.3048 m exactly). Similarly, 1 hectare = 10,000 m², 1 square kilometer = 1,000,000 m², and 1 square mile = 5280² × 0.3048² m².
Regional units are also supported: the rai (Thailand, 1 rai = 1,600 m²), the Indian cent (1/100 of an acre, ≈ 40.47 m²), and the Pakistani/Indian marla (≈ 25.29 m², based on 272.25 sq ft per marla). These definitions are the most common standards but local customs can vary, so verify with your local authority for survey-grade work.
For irregular plots, divide the parcel into simpler shapes (rectangles, triangles), calculate each in a consistent unit, sum them, then convert the total. For GPS-grade precision, use a licensed surveyor or a dedicated GIS tool.

One acre contains exactly 43,560 square feet. This is also equal to 4,046.856 square meters or 0.404686 hectares. A square one acre in size would measure about 208.7 ft × 208.7 ft.
A hectare equals 10,000 m² (100 m × 100 m), while an acre equals 4,046.856 m². One hectare is therefore about 2.471 acres, or one acre is roughly 0.4047 hectares. Hectares are standard in most countries; acres are used mainly in the US and UK.
One acre equals 160 marla when using the standard Pakistani/Indian definition of 1 marla = 272.25 sq ft (25.293 m²). Local definitions can differ slightly, so confirm with your local land registry.
