About Land Units

Land Units explains the units Indians use for land (bigha, biswa, kanal, marla, guntha, cent, katha, nali and more) and converts between them.

Where the sizes come from

A local unit is only as good as its source. Every size in the converter was read by us in one of these documents on 11 November 2026:

• Fixed by definition: the international yard is exactly 0.9144 metre, a square yard is 9 square feet and an acre is 4,840 square yards.
• Meta Data and Data Standards (MDDS), Annexure IV, code directory CD00.01 Measurement units, Table 1.3 Conversion Factors. Ministry of Electronics and IT, Government of India; the table credits the Department of Land Resources. Open the document
• Statistical Handbook of Meghalaya 2023, Directorate of Economics and Statistics, Government of Meghalaya, conversion table. Open the document
• Revenue Records and Arrangement of Holdings (training material), Uttarakhand Academy of Administration, Nainital, conversion page. Open the document

Where the documents round a figure (for example "1 cent = 40 square metres"), we use the exact value that follows from the acre.

What we left out, on purpose

Bigha, katha and similar units change between states and districts. For Uttar Pradesh, Bihar, West Bengal, Madhya Pradesh, Gujarat, Himachal Pradesh, Odisha and others we did not find an official table that we could open and read, so we print no number for them. Units such as the ground, ankanam, dhur and chatak are left out for the same reason. The converter lets you type the size of your own local unit instead. Punjab's own table could not be opened on the day we checked; the kanal and marla values are those the national standard lists for Haryana.
