Square foot

The square foot is the unit built area is quoted in, and it is exactly one ninth of a square yard. This page converts it into everything else, so a land quote and a construction quote can be read against each other.

How many square feet

Bigha has no fixed legal size. Around 2,500 sq yd is the figure commonly used around Dholera. Change it to whatever your deed actually says.

The unit built area is quoted in

A square foot is exactly one ninth of a square yard and 0.09290304 square metres. It is the unit apartment and construction brochures use, which is why a plot quote and a built area quote in the same document can look like they are describing wildly different things.

43,560 square feet make an acre. 1,089 make a guntha. At the 2,500 square yard convention, 22,500 make a bigha. The first two of those are exact and the third depends entirely on the convention.

Watch the difference between land and building. A rate per square foot of land and a rate per square foot of built up area are different prices for different things, and a brochure that quotes both without saying which is which is worth a question. Ask which area the rate applies to and get the answer in writing.

One square foot, exactly

The 43,560 row is exactly one acre. The 22,500 row is one bigha at the 2,500 square yard convention.

Where this comes from

The exact foot CONFIRMED NIST Office of Weights and Measures, SI units of length. Federal Register notice of 30 June 1959.
1 foot = 0.3048 metres exactly, effective 1 July 1959, so 1 sq ft = 0.09290304 sq m exactly.
43,560 sq ft to the acre and 1,089 sq ft to the guntha DERIVED
4,840 sq yd and 121 sq yd, each multiplied by 9.
