Karnataka Land Area Converter — Guntha, Cent
Karnataka's land revenue records — the RTC (Record of Rights, Tenancy and Crops), also called Pahani — measure agricultural and converted land in Acres and Guntha, not just Acres. A typical RTC entry reads something like "2 Acres 15 Guntha," meaning 2 full acres plus an additional 15 Guntha. Getting the Guntha-to-square-feet conversion right matters when you're verifying a survey number against a sale deed or khata certificate.
Guntha, Bigha, and Katha values vary by state. Using Standard (Karnataka / Maharashtra / pan-India reference) standard — 1 Bigha = 27,225 sq ft, 1 Katha = 720 sq ft, 1 Guntha = 1,089 sq ft. Source: Karnataka RTC land-record standard (Guntha); commonly published pan-India reference (Bigha/Katha).

Why Karnataka's Units Differ
Unlike Bigha or Katha, Guntha is unusually consistent: Karnataka, Maharashtra, Andhra Pradesh, and Telangana all define 1 Guntha as 1/40th of an acre — a 33 ft × 33 ft square, or 1,089 sq ft. Karnataka's real difference is Cent, which shows up far more often in coastal Karnataka (Mangaluru, Udupi) than in Bangalore or the interior, largely because of the region's proximity to Kerala, where Cent (1/100 acre = 435.6 sq ft) is the default small-plot unit.
Unit-by-Unit Reference
Guntha
1 Guntha = 1,089 sq ft = 101.17 sq m = 1/40 acre.
Used throughout Karnataka's RTC and Pahani land records for both agricultural and converted (non-agricultural) land. 40 Guntha make one acre exactly, so a plot recorded as "1 Acre 20 Guntha" is 1.5 acres.
Cent
1 Cent = 435.6 sq ft = 40.47 sq m = 1/100 acre.
More common in coastal Karnataka (Dakshina Kannada, Udupi) than in Bangalore, where Guntha and direct square-feet pricing dominate. Cent is popular for smaller residential plots — a "5 Cent site" is 2,178 sq ft.
