Area Converter

How to use the Area Converter

1. Type the area you have.
2. Choose the unit it is in, for example acre or gunta.
3. Choose the unit you want, for example square feet.
4. Read the result. The reference table shows common values for the units you picked.

Formula used

Result = Value × (sq m per source unit ÷ sq m per target unit). 1 sq ft = 0.09290304 sq m, 1 gaj = 9 sq ft, 1 cent = 435.6 sq ft, 1 gunta = 1089 sq ft and 1 acre = 43,560 sq ft.

Worked example

Here is the Area Converter worked through with the example values shown above, so you can check each step by hand.

Quick reference table

Common values converted with the units selected above.

The conversions you will use most

One acre is 43,560 square feet, which is also 4,046.9 square metres and 0.4047 hectares. One hectare is 2.471 acres. One cent is 435.6 square feet, so 100 cents make an acre. One gunta is 1,089 square feet, and 40 guntas make an acre.

One gaj (square yard) is 9 square feet, so a 200 gaj plot is 1,800 square feet. One square metre is 10.764 square feet.

Carpet area, built-up area and plot area

The unit is only half of the story. In apartments, carpet area is the usable floor space inside the walls, built-up area adds the walls and balconies, and super built-up area adds a share of common spaces. Prices per square foot can look similar while the usable space differs a lot.

Always ask which area a price refers to. Convert all offers into the same unit and the same type of area before you compare.

Land units that vary by state

Some units are not the same everywhere. A bigha, for example, differs between states and even between regions, and kanal and marla also vary in practice. For this reason they are not included. If your land record uses such a unit, ask the local revenue office or check the record for its square foot or square metre equivalent.

The units in this converter, square feet, metres, gaj, cents, guntas, acres and hectares, have fixed definitions and are safe to use for comparison.

Worked example

A farmland listing shows 12 guntas. In square feet that is 13,068, and in acres it is 0.3. At ₹2,000 a square foot, the total would be ₹2,61,36,000.

For legal and registration purposes, use the figures on the title documents rather than a conversion.

Land measurement in practice

Land is measured in different units in different regions. One acre is 43,560 square feet, which is about 4,047 square metres, and one hectare is 10,000 square metres, or about 2.47 acres. In many parts of India, land is also measured in cents, guntas, and square yards (gaj). The exact size of a gunta (1,089 square feet) and a cent (435.6 square feet) is the same across the states that use them, but local custom for other units varies.

For a legal transaction, always rely on the area in the title deed and the survey records, and check whether the figure is built-up area, carpet area or plot area. This converter helps with comparison and planning, and does not replace a survey.
