Land measurement in India is uniquely complex. The same unit — bigha — covers an area of 6,804 sq ft in Uttarakhand and 27,225 sq ft in Bihar. Marla in Punjab equals 272.25 sq ft, while katha carries different values in Bengal, Bihar, and Assam. This category covers every Indian land unit in use today, with state-specific conversion factors sourced from official revenue department records.
Whether you are reading a sale deed, calculating farm loan eligibility, preparing for a revenue inspector exam, or verifying a RERA-registered plot's carpet area, you need the right number for the right state. Generic calculators that assume a fixed bigha value will mislead you. Our calculators are region-specific.
Most Used Land Converters
The most frequently searched land conversions in India involve bigha to square feet across states — UP, Bihar, Rajasthan, Bengal, and Assam each have their own standard. Acre and hectare are the metric anchors used in official government documents, RERA filings, and bank loan applications.
Kanal and marla are dominant in Punjab and Haryana. Cent and ground are the units of choice in Tamil Nadu and Kerala. Ankanam and kuncham serve Andhra Pradesh and Telangana. Every region has its unit — and each unit has a precise, verifiable sq ft value.
Land Units and Official Standards
The Real Estate (Regulation and Development) Act 2016 requires carpet area disclosure in square meters for all RERA-registered projects. The Standards of Weights and Measures Act 1976 mandates metric for official transactions, but state revenue acts continue to recognise local units for land records.
The National Land Records Modernisation Programme (DILRMP) is digitising records across states. As records go digital, both local and metric area values appear side by side. Knowing how to cross-verify the two is increasingly important for buyers, sellers, and legal professionals.
For Competitive Exam Preparation
Land unit conversions appear in Revenue Inspector, Patwari, and Lekhpal recruitment exams in nearly every state. UPSC Geography and General Studies papers test awareness of standard conversions. SSC and IBPS quantitative aptitude sections include multi-step land area problems.
Key values to memorise: 1 acre = 43,560 sq ft = 0.4047 hectares. 1 hectare = 107,639 sq ft = 2.471 acres. From these two anchors, you can derive any metric land conversion. State-specific units require separate memorisation — use the state-wise tables on individual calculator pages.
