Dhurki is the smallest traditional land measurement unit used in Bihar. If you're dealing with small plots, homestead land, or subdivided agricultural parcels in rural Bihar, you'll frequently encounter this term in property documents and revenue records.
Here's the quick math: 1 Dhurki = 3.403 square feet. That's roughly the size of a small bathroom tile — really tiny. But when you're measuring land boundaries or settling inheritance disputes in villages, these small increments matter a lot.
The Dhurki fits into Bihar's land measurement hierarchy like this: 20 Dhurki makes 1 Dhur, 20 Dhur makes 1 Katha, and 20 Katha makes 1 Bigha.
While 3.403 sq ft (based on 1 Dhur = 68.06 sq ft) is the most widely accepted value, some districts in Bihar use slightly different values. For instance, in Samastipur district, 1 Dhur is officially 75 sq ft, making 1 Dhurki = 3.75 sq ft there. Always confirm with your local revenue office.
Square Feet = Dhurki × 3.403
Example: 100 Dhurki × 3.403 = 340.3 Sq Ft
Dhurki = Square Feet ÷ 3.403
Example: 1,000 Sq Ft ÷ 3.403 = 293.86 Dhurki
The derivation is straightforward: since 1 Dhur = 68.06 sq ft in Bihar and 1 Dhur = 20 Dhurki, we get 68.06 ÷ 20 = 3.403 sq ft per Dhurki.
| Dhurki | Square Feet | Dhur | Katha |
|---|---|---|---|
| 1 | 3.403 | 0.05 | 0.0025 |
| 5 | 17.015 | 0.25 | 0.0125 |
| 10 | 34.03 | 0.5 | 0.025 |
| 20 (1 Dhur) | 68.06 | 1 | 0.05 |
| 50 | 170.15 | 2.5 | 0.125 |
| 100 | 340.3 | 5 | 0.25 |
| 400 (1 Katha) | 1,361.25 | 20 | 1 |
| 1,000 | 3,403 | 50 | 2.5 |
| 8,000 (1 Bigha) | 27,225 | 400 | 20 |
Bihar uses a base-20 system. Every unit is 20 times the previous one. Here's the full hierarchy:
| Unit | Sq Ft | Equals | Dhurki |
|---|---|---|---|
| 1 Dhurki | 3.403 | Smallest unit | 1 |
| 1 Dhur | 68.06 | 20 Dhurki | 20 |
| 1 Katha | 1,361.25 | 20 Dhur | 400 |
| 1 Bigha | 27,225 | 20 Katha | 8,000 |
| 1 Acre | 43,560 | 1.6 Bigha | 12,800 |
People often mix up Dhurki and Dhur. They sound similar, but the difference is huge — a Dhur is 20 times larger than a Dhurki:
When reading property documents, pay close attention to whether it says "Dhurki" or "Dhur." Confusing the two could mean a 20× error in your land calculation. If you're unsure, verify with the Bihar Bhumi Jankari portal.
1 Dhurki equals 3.403 square feet. This is derived from the Bihar standard where 1 Dhur = 68.06 sq ft and 1 Dhur = 20 Dhurki. So 68.06 ÷ 20 = 3.403 sq ft per Dhurki.
400 Dhurki make 1 Katha. Since 1 Katha = 20 Dhur and 1 Dhur = 20 Dhurki, you get 20 × 20 = 400 Dhurki per Katha = 1,361.25 square feet.
8,000 Dhurki = 1 Bigha in Bihar. The math: 1 Bigha = 20 Katha = 400 Dhur = 8,000 Dhurki = 27,225 sq ft ≈ 0.625 Acres.
Yes. The most common value is 3.403 sq ft (based on 1 Dhur = 68.06 sq ft). But some districts like Samastipur use 1 Dhur = 75 sq ft, making 1 Dhurki = 3.75 sq ft. Always check with your local circle office.
Jharkhand uses the Dhur-Katha-Bigha system but typically doesn't subdivide below Dhur. The Dhurki unit is specific to Bihar's traditional measurement practices, primarily in rural areas.
Square Feet = Dhurki × 3.403. That's it. For the reverse: Dhurki = Square Feet ÷ 3.403. These formulas use the standard Bihar conversion rate.
