Indian Land Area Converter
Bigha, kanal, marla, guntha, cent, katha, biswa, ground and gaj, in square metres, square feet and acres. A bigha is not one size: it is a different area in Uttar Pradesh, in Bengal and in Rajasthan, so this page makes you pick the state and then prints the figure it used.
Area
This sets bigha, katha, biswa and the units under
them. Nothing else on the page moves when you change it.
The second is the marla used in Pakistani
development schemes such as DHA. Indian revenue records use the
first.
Or a plot, by its sides
Fill both and the rectangle they describe is used
instead of the box above. Leave either empty and it is ignored.
A rectangle, not a plot boundary
This multiplies two sides. Real plots are rarely
true rectangles, and a deed's stated area is the one that counts;
treat this as the size of the rectangle you described and nothing
more.

What those local units mean here
Where these figures come from, and what varies
Two exact definitions carry everything else. A yard is 0.9144
metres exactly and a foot is 0.3048 metres exactly, so a square foot is
0.09290304 square metres and a square yard is nine square feet. Every
traditional unit below is a whole number of square feet or square yards,
which is why the acre, kanal, guntha and cent rows come out as round
numbers and not as approximations.
The units that do not vary anywhere: 1 acre = 43,560 sq ft = 4,840 sq yd; 1 guntha = 1,089 sq ft, and 40 guntha make an acre; 1 cent — also called a dismil or a decimal — is one hundredth of an acre, 435.6 sq ft; 1 ground = 2,400 sq ft, used in and around Chennai; 1 ankanam = 72 sq ft = 8 sq yd; 1 kuncham = 4,356 sq ft, which is ten cents; 1 killa is an acre by another name, and 1 murabba is 25 killa. One gaj is a square yard.
Kanal and marla split two ways. In the revenue records of Punjab, Haryana, Himachal and Jammu and Kashmir — and in Pakistani revenue records too — 1 marla = 30.25 sq yd = 272.25 sq ft, 20 marla make a kanal of 5,445 sq ft, and 8 kanal make an acre exactly. Pakistani housing schemes instead sell a marla of 25 sq yd = 225 sq ft and a kanal of 500 sq yd = 4,500 sq ft. A five marla plot is therefore either 1,361 or 1,125 sq ft depending on which is meant, and that is a real 21% difference, not a rounding. Pick the one your paperwork uses.
Bigha is not a unit, it is a family of them. It was never standardised nationally, and the figures used here are the ones the state revenue conventions settle on: Uttar Pradesh pucca 27,225 sq ft (3,025 sq yd, five eighths of an acre) and kachha exactly one third of that; Bihar and Jharkhand 27,225 sq ft, divided into 20 katha; West Bengal 14,400 sq ft (1,600 sq yd), divided into 20 katha of 720 sq ft and 16 chatak to the katha; Assam 14,400 sq ft, but divided into 5 katha of 2,880 sq ft; Rajasthan pucca 27,225 sq ft and kachha 17,424 sq ft (two fifths of an acre); Gujarat 17,424 sq ft; Madhya Pradesh 12,000 sq ft; Punjab and Haryana 9,075 sq ft, the kachha bigha, one third of the pucca one — sources that round 1,008⅓ sq yd down to 1,008 print 9,072 sq ft instead; Himachal Pradesh 8,712 sq ft, one fifth of an acre; Uttarakhand 6,806.25 sq ft, a quarter of the pucca bigha, alongside the hill unit nali of 2,160 sq ft.
Below the district level this stops being reliable, and no converter can fix that. In Bihar the katha is quoted anywhere from about 750 to 2,000 sq ft depending on the district; western Uttar Pradesh and eastern Uttar Pradesh do not agree on the kachha bigha either. What is written on the sale deed, the khasra or the 7/12 extract is the area you own. This page is for reading an advertisement, not for settling a boundary.
Figures are rounded to six significant digits, except that a whole number is never shortened: a square kilometre is shown as 10,763,910 square feet, not as 10,763,900. Nothing here is ever written in scientific notation, because 1.0763910417e7 is not a number anyone can read and not one anyone can screenshot. Conversion goes through square feet, so a value typed in one unit and read back in the same unit comes back as what you typed, to the six digits shown.
