There is no single national answer to 20 bigha to acre. The figure ranges from 3.125 to 12.5, and which one applies depends entirely on the state the land is in. In Uttarakhand it comes to 3.125, while in Uttar Pradesh the same quantity is 12.5 — a difference of roughly 4 times. The reason is straightforward: an acre is fixed worldwide at exactly 43,560 square feet, but the bigha is a customary unit that each state defined for itself long before the metric system arrived. Several states run more than one convention at once — a pucca and a kaccha bigha, or separate hill and plain measures — so the state alone does not always settle it. These are commonly-cited reference figures derived from each state's traditional definition, not legal standards: the area recorded by your district land revenue office is what governs any transaction.
