Why it Matters

Land and area come in a confusing mix of units — a builder quotes square feet, a deed lists acres, a farmer talks in guntha or bigha, and a map uses hectares. Converting between them by hand means juggling odd factors like 4046.86 m² per acre. An instant area converter removes the guesswork, which matters most for property deals and farming where a conversion slip can mean a costly mistake.

What this tool does

The Area Converter turns any area value into every other common area unit at once. Type a number into one unit and the rest of the list updates instantly — square metres, square feet, acres, hectares, and the Indian land units guntha, cent, and bigha.

It’s built for the messy reality of land measurement, where a single plot might be described in square feet by a builder, acres on a deed, and bigha by a local farmer.

Common conversions at a glance

  • 1 acre = 43,560 ft² = 4046.86 m² = 40 guntha = 100 cent
  • 1 hectare = 10,000 m² ≈ 2.47 acres
  • 1 guntha = 1089 ft² ≈ 101.17 m²
  • 1 bigha (pucca, 3025 yd²) ≈ 2529.29 m²

A note on bigha

Bigha has no single national definition — it varies from about 1,300 m² to nearly 2,900 m² depending on the state and whether it’s a kaccha or pucca bigha. This converter uses the pucca bigha of 3025 square yards. For any legal or official land transaction, always confirm the bigha definition used in that specific district.

Privacy

Every conversion runs in your browser via the pure convertArea function. Typing produces zero network requests — you can verify this in your browser’s Network tab.

Frequently Asked Questions

How many square feet are in an acre?
One acre is 43,560 square feet, which is 4046.8564 square metres. It's also exactly 40 guntha and 100 cent. The acre traces back to the area a yoke of oxen could plough in a day, which is why it isn't a round metric number.
What is a guntha?
A guntha is an Indian land unit equal to 1089 square feet (about 101.17 square metres). There are 40 guntha in an acre, so it's a convenient sub-division for farm and plot sizes in states like Maharashtra and Karnataka. This converter uses the exact 1089 ft² definition.
Why does bigha vary, and which value do you use?
Bigha is a traditional unit with no single national definition — it differs widely by state, from roughly 1,300 m² in West Bengal to about 2,500–2,900 m² in parts of North India. This tool uses the pucca bigha of 3025 square yards (≈ 2529.29 m²). Always confirm the local definition for any official or legal land measurement.
What's the difference between a hectare and an acre?
A hectare is a metric unit equal to 10,000 square metres (a 100 m × 100 m square). An acre is about 4046.86 square metres, so one hectare equals roughly 2.47 acres. Hectares are standard in scientific, agricultural, and international contexts; acres are common in the US, UK, and India.
Is the conversion exact?
Yes — the tool uses exact SI conversion factors (for example, 1 ft² = 0.09290304 m²) and displays results to 8 significant figures. For the unit definitions that are themselves exact, the conversions are exact; only the display is rounded.
Are my entries sent anywhere?
No. All conversion runs in your browser via the pure `convertArea` function. There are no network calls — you can confirm this in your browser's Network tab.
