Square Kilometre to Bigha by state
Because the bigha differs from state to state, the table below gives the value in each state we cover. The square-foot column is the standard defining value; the metre and conversion columns are computed from it.

Indian land units vary by state and even by district, and local custom can differ from the standard value. For any legal, property or financial purpose, confirm the value against your local revenue records (patwari / tehsil) before relying on it.
About square kilometre and bigha

Bigha: A bigha is a traditional Indian land unit whose size is not standardised — it ranges from roughly 1,500 to 2,530 m² depending on the state and on whether a "pucca" (large) or "kachha" (small) bigha is meant.

Where the sources agree — and where they don’t
We record a confidence level for every regional value from our research pass, and we publish it rather than hiding it. High means multiple independent references matched. Medium means the value is well attested but corroboration is thinner, so treat it as indicative and confirm against your local record.
| Region | 1 square kilometre in sq ft | Confidence |
|---|---|---|
| Uttar Pradesh, Bihar & Rajasthan (pucca) | 27225 | High |
| Rajasthan (kachha) | 17424 | High |
| Uttar Pradesh (kachha, western UP) | 9075 | Medium |
| West Bengal | 14400 | High |
| Assam | 14400 | High |
| Madhya Pradesh | 12000 | High |
| Himachal Pradesh (1/5 acre) | 8712 | High |
| Gujarat (vigha) | 17424 | High |
| Haryana & Punjab (kachha basis) | 9075 | Medium |

Because the documented values genuinely differ between regions, we show each variant instead of averaging them into a single number. An average would be wrong everywhere.
- Haryana & Punjab (kachha basis): Bigha is not standardised in Haryana/Punjab — local 1/5, 1/4 and 1/2-acre bighas (8,712 / 10,890 / 21,780 sq ft) also exist. Confirm against local records.
- Haryana & Punjab (pucca basis): Bigha is not standardised in Haryana/Punjab — several local bases exist. Confirm against local records.
What this converter does not account for
- Local custom below state level. Districts and even individual villages can use a different working value from the state norm. The figure here is the state-level standard.
- Values marked medium confidence. These are the ones most worth checking against your own paperwork before you rely on them.
- Historic and pre-survey records. Older deeds may use a value that predates the current survey settlement for that area.
- Legal and transactional use. This is a calculation aid, not a legal document. For a sale, mutation or dispute, the figure that governs is the one in your official land record.
- Rounding in the displayed result. The underlying maths runs at full precision; what you see is rounded for readability, so a long chain of manual conversions may drift slightly.
