Bigha to acre, hectare, square feet: how to convert

Worked examples for the most common bigha conversions — for every state where the unit is used.

Last updated: 19 May 2026

Bigha is a customary unit, not a standardised one. Before you can convert it to anything else, you need to know which bigha you are working with — the value differs significantly by state. Once you have that, conversion is just multiplication.

This guide gives you the formula, the per-state values, and worked examples for the conversions buyers most often need.

The conversion formula

Every conversion routes through square feet (sqft) as the anchor unit. So:

  • Bigha → sqft = bigha-count × your-state-bigha-in-sqft
  • Bigha → sqm = (bigha × state-bigha-sqft) ÷ 10.7639
  • Bigha → acre = (bigha × state-bigha-sqft) ÷ 43,560
  • Bigha → hectare = (bigha × state-bigha-sqft) ÷ 107,639

State-specific bigha values

  • Madhya Pradesh — 27,225 sqft
  • Uttar Pradesh — 27,000 sqft (pucca)
  • Bihar — 27,220 sqft
  • Rajasthan — 27,225 sqft (pucca)
  • Gujarat — 17,427 sqft
  • West Bengal — 14,400 sqft
  • Assam — 14,400 sqft

Worked examples

1 bigha in Madhya Pradesh

  • = 27,225 sqft
  • = 27,225 ÷ 10.7639 ≈ 2,529 sqm
  • = 27,225 ÷ 43,560 ≈ 0.625 acre (5/8 of an acre)
  • = 27,225 ÷ 107,639 ≈ 0.253 hectare

2 bigha in Uttar Pradesh

  • = 2 × 27,000 = 54,000 sqft
  • = 54,000 ÷ 10.7639 ≈ 5,016 sqm
  • = 54,000 ÷ 43,560 ≈ 1.24 acre

5 bigha in West Bengal

  • = 5 × 14,400 = 72,000 sqft
  • = 72,000 ÷ 43,560 ≈ 1.65 acre
  • = 72,000 ÷ 107,639 ≈ 0.669 hectare

Notice that 5 bigha in West Bengal (1.65 acre) is smaller than 2 bigha in UP (1.24 acre) is — wait, the other way: 5 WB bigha equals roughly 1.65 acre, only slightly more than the 2 UP bigha at 1.24 acre. WB bigha is much smaller than UP bigha, so 5 of the WB ones is only about a third more land than 2 of the UP ones. This is exactly the kind of confusion the calculator below removes.

1 acre in MP

Going the other way: 1 acre = 43,560 sqft. Divided by MP bigha (27,225 sqft): 1.6 MP bigha per acre. So a 2.5-acre farm in MP is 4 bigha.

Reverse conversions

If your input is in sqft / sqm / acre / hectare and you want bigha:

  • sqft → bigha = sqft ÷ your-state-bigha-in-sqft
  • acre → bigha = (acre × 43,560) ÷ your-state-bigha-in-sqft
  • hectare → bigha = (hectare × 107,639) ÷ your-state-bigha-in-sqft

Skip the math

The Settelo Plot Area Converter handles all of this — pick your state, pick your unit, type the value, and it shows you the equivalent in sqft, sqm, gaj, acre, and hectare simultaneously.
