Area Converter

What this tool does

Area Converter changes land and floor areas between metric, imperial and traditional Indian units. Standard units use exact definitions, and regional units like bigha are labelled with the definition used so you know exactly what you are converting.

Property listings, building plans and land records rarely use the same unit. Apartments in India are sold by the square foot, plots by the gaj (square yard), farmland by the acre, bigha or guntha, and official surveys in hectares. Converting between them by hand is error-prone because area factors are the square of length factors: 1 metre is 3.28 feet, but 1 square metre is 10.76 square feet.

This converter uses exact values built on the international foot of 0.3048 m: a square foot is 0.09290304 m², an acre is 4,046.8564224 m² and a hectare is 10,000 m². For Indian units it uses widely published standards: cent is one hundredth of an acre (435.6 sq ft), guntha is 1,089 sq ft, marla is 272.25 sq ft and kanal is 20 marla. Bigha is shown in two labelled versions because its size changes from state to state.

How to use Area Converter

1. Enter the area in the Value field.
2. Select the unit in From, such as Square foot or Bigha.
3. Select the target unit in To and read the Result.
4. Use the swap button to convert the other way, and adjust Decimal places as needed.
5. Look at the full table to compare the area in every unit, including acres and hectares.
6. Paste a list of plot or flat sizes into Batch convert and download them as CSV.

Tips for better results

• One acre is 43,560 sq ft and one hectare is about 2.471 acres.
• A square gaj is the same as a square yard: 9 sq ft or about 0.836 m².
• For apartments, check whether the figure is carpet, built-up or super built-up area before comparing prices.
• If your land record uses a local bigha, enter its square-foot size and convert from square feet instead.

Common use cases

• Comparing flat sizes quoted in square feet with brochures quoted in square metres.
• Converting plot sizes in gaj or marla to square feet for construction estimates.
• Translating farmland between acres, hectares, guntha and cent.
• Converting flooring or paint coverage figures between ft² and m².

Common mistakes to avoid

• Converting area with a length factor, for example multiplying square metres by 3.28 instead of 10.764.
• Assuming a bigha is the same everywhere; it ranges widely between states and districts.
• Comparing carpet area in one listing with super built-up area in another.
