Converting acre to bigha is common in real estate, agriculture, surveying, and construction. Property listings, land records, and planning documents often use different area units depending on the country or industry — making accurate conversion essential for cross-border transactions and international comparisons.
As a practical reference: 5 ac = 8 bigha and 10 ac = 16 bigha. For larger land areas, 100 ac = 160 bigha — a common benchmark for farm and estate valuations. The reverse: 1 bigha = 0.625 ac.
All conversions use the internationally recognized factor of exactly 1 ac = 1.6 bigha. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.
Formula: Bigha = Acre × 1.6000047
Multiply any acre value by 1.6000047 to get bigha. One acre equals 1.6000047 bigha.
Reverse: Acre = Bigha × 0.62499815
Acres × 1.6 = bighas (UP standard). Simple multiplication.
One acre = 1.6 bighas — remember the 1.6 multiplier.
Bighas × 0.625 = acres.
Measures crop fields and pasture in acres for planting, yield, and subsidy calculations.
Lists rural and suburban land parcels in acres for US and UK property transactions.
Measures and certifies plot areas in acres for legal property registration.
Assesses collateral value of farmland and rural property quoted in acres.
Allocates land parcels for development, conservation, or infrastructure in acres.
Converts acres to local Indian units like bigha, cent, or guntha for local transactions.
The acre is a unit of land area equal to 43,560 square feet or about 4,047 m². Its origins trace to medieval England where it represented the amount of land an ox could plough in a day.
Acres remain the standard land measurement unit in the US, UK, Canada, and India for agriculture, real estate, and property transactions.
Interesting fact: A US football field (including end zones) is about 1.32 acres, and a typical suburban house plot in the US is roughly 0.2 acres.
The bigha is a traditional South Asian unit of land area whose size varies significantly by region. In West Bengal, 1 bigha = 1,600 m²; in Uttar Pradesh, 1 bigha ≈ 2,529 m²; in Rajasthan, it can be larger.
Bigha is widely used across India, Nepal, and Bangladesh for agricultural land measurement in rural property transactions and government land records.
Interesting fact: The bigha is not standardized — its size varies from 843 m² (in Himachal Pradesh) to 3,025 m² (in some parts of Rajasthan), making local context essential.
