Bigha to Square Feet Converter — Bihar

In Bihar, rural and peri-urban plots are frequently described in Bigha–Kattha–Dhur. The widely used practical standard is:

• 1 Bigha = 20 Kattha
• 1 Kattha = 20 Dhur
• 1 Bigha ≈ 27,225 square feet (so 1 Kattha ≈ 1,361.25 sq ft)

That means 1 Acre (43,560 sq ft) is about 1.6 Bigha or 32 Kattha in Bihar. Buyers comparing a Patna outskirts plot listed in Kattha with a city flat brochure listed in sq ft should convert both sides before negotiating.

Always cross-check the circle rate / stamp duty notification for your district. Local practice can use the same unit names with slightly different rods historically; for online estimates, the 27,225 sq ft Bigha is the common reference used across Bihar converter tools.

When reading a Bihar sale deed or family partition note:

1. Confirm whether the area is written in Bigha, Kattha, or Decimal/Dismil in newer papers.
2. Convert everything to square feet once, then to acre — do not mix Kattha from Bihar with Kattha from West Bengal (those are different sizes).
3. For bank valuation or online listing portals, brokers often restate Bihar Kattha as sq ft; verify the multiplier (≈1,361.25) rather than assuming 720 or 1,350 from another state.

This converter locks the Bihar standard so you do not accidentally apply a West Bengal or Punjab Bigha size to a Bihar plot.
