Bigha, kanal, guntha, cent, gaj, acre and hectare, with each state’s official figure
Runs in your browser. Nothing you type is sent anywhere. Checked against sources on 29 Sept 2026.Choose a state, enter an area in any unit, and see every other unit at once. A West Bengal or Assam bigha is 14,400 sq ft, a Haryana kanal is 5,445 sq ft, a guntha is 1,089 sq ft and a cent is 435.6 sq ft. Local units appear only where the state publishes an official figure.
Pick the State, since bigha, guntha and other local units differ by state.
Enter the Area and choose its Unit.
Choose the unit to Convert to, or press Swap to reverse the two.
Read the converted area, then press Share result; the figures come from the state sources listed under Sources.
Square feet, square metres, square yards, acres and hectares are fixed by international definition: a foot is exactly 0.3048 metre, so an acre of 43,560 square feet is exactly 4,046.8564224 square metres. Those conversions are the same in every state and come from NIST Handbook 44, Appendix C. A gaj is the everyday name for a square yard, 9 square feet.
Local units are different. The bigha, kanal, katha, guntha and their smaller parts grew out of local measuring rods, and the same word means different areas in different places. A bigha is 14,400 square feet in West Bengal and Assam, 9,075 square feet in Haryana's older records, and anything from 8,100 to 27,225 square feet in Himachal Pradesh depending on the district. A converter that shows one bigha for all of India is wrong for most of it.
What this page includes. A state's local units appear only when we found the figure in a state or central government document: a revenue department table, a registration directorate FAQ, a state gazetteer, a land records manual or an audit report. Each state's sources are linked in the table under the converter. Bihar's glossary gives the kattha only approximately, for Patna, so those figures are marked approximate.
What it leaves out. Uttar Pradesh, Rajasthan, Punjab, Gujarat, Madhya Pradesh and several other states are not included, because the only tables we could find were copied from site to site with no official source behind them. The maund and seer are also missing on purpose: they are weights, not areas.
Before you rely on a figure, check the unit written in your own land record. Old records in the same state can use a different measuring rod from new ones, and the revenue office's figure for your village is the one that counts in a sale or a dispute.
The answer depends on the state. West Bengal and Assam publish the bigha as 14,400 square feet. Haryana's pre-settlement bigha is 9,075 square feet, 4.8 to the acre. Himachal Pradesh uses 8,100, 9,075 or 27,225 square feet by district. Bihar's glossary gives about 27,220 square feet around Patna. Choose your state to see its figure.
Haryana's land records define 20 marla to the kanal and 8 kanal to the acre. A marla is 9 sarsai of 5.5 by 5.5 feet, which is 272.25 square feet, so a kanal is 5,445 square feet or 605 square yards. Himachal Pradesh uses the same figures where the 66-inch karam applies.
A guntha is 121 square yards, the square on one 11-yard surveyor's chain, so it is 1,089 square feet and 40 guntha make an acre. A cent is one hundredth of an acre, 435.6 square feet or about 40.47 square metres. Both are fixed fractions of the acre wherever they are used.
A state appears only when we found its local units in an official state or central government document. For Uttar Pradesh, Rajasthan, Punjab, Gujarat, Madhya Pradesh and several others, the only tables available were unsourced copies, and a wrong bigha can cost real money in a land deal. Standard units still work for every state.
No. Maund and seer measure weight, not area, so there is no correct way to turn them into acres or bighas. A maund of wheat is a quantity of grain, not a piece of land. Use a weight converter for those, and this page for the area of the land itself.
Your land record and the local revenue office decide. This page shows the official state figures we could source, but the sources themselves say local measures can differ between districts and between old and new settlements. Check which unit and which measuring rod your jamabandi, khatiyan or 7/12 extract uses.
Rates and rules change; check the source before you rely on a figure.
