Bigha to Acre Converter — India & Nepal Conversion Table

1 Bigha (India, 1,600 gaj) ≈ 0.3306 acre · 1 Bigha (Nepal Terai) ≈ 1.6736 acre

Bigha to acre is one of the most common land conversions in South Asia, and also one of the easiest to get wrong. The acre is fixed everywhere in the world at 43,560 square feet, but the bigha is a traditional unit whose size depends on where the land is. A seller in Assam, a bank officer working from a metric survey record, and a relative in Nepal can all say "bigha" and mean three different areas.

This page uses the two definitions supported by our land area converter: the common Assam/West Bengal figure of 14,400 sq ft (1,600 gaj) for India, and the standard Terai figure of 72,900 sq ft for Nepal. If your land is in a state that uses a different bigha — Bihar, Uttar Pradesh, Rajasthan, and Gujarat all do — read the state-wise bigha guide first, then apply the same formula with your local figure.

The formula

Acres = Bigha × (bigha size in sq ft) ÷ 43,560

India (1,600 gaj bigha): Acres = Bigha × 14,400 ÷ 43,560 = Bigha × 0.3306

Nepal (Terai bigha): Acres = Bigha × 72,900 ÷ 43,560 = Bigha × 1.6736

Reverse: Bigha = Acres × 43,560 ÷ (bigha size in sq ft)

Worked examples

Example 1 — selling 5 bigha in West Bengal

A plot recorded as 5 bigha in a West Bengal deed uses the 14,400 sq ft bigha. 5 × 14,400 = 72,000 sq ft, and 72,000 ÷ 43,560 = 1.65 acres. A buyer comparing it against an acre-priced listing should treat it as roughly one and two-thirds of an acre.

Example 2 — a 2 bigha plot in the Nepal Terai

In Jhapa or Rupandehi, 2 bigha means 2 × 72,900 = 145,800 sq ft, which is 145,800 ÷ 43,560 = 3.35 acres — more than ten times the area the same words would describe in Kolkata. This is why quoting the region alongside the bigha figure matters.

Good to know

The bigha has no national standard in India. The 14,400 sq ft figure used here is the Assam/West Bengal convention; Bihar's bigha is roughly 27,220 sq ft, Gujarat's about 17,424 sq ft, and Himachal Pradesh uses 8,712 sq ft (exactly 1/5 acre). Always confirm which bigha your land record uses before signing anything — the India land units guide lists the common figures side by side.
