Kattha to Square Feet — 1 Kattha (Nepal) = 3,645 Sq Ft

1 Kattha (Nepal) = 3,645 sq ft = 338.63 m² = 20 Dhur · 20 Kattha = 1 Bigha

In Nepal's Terai plains — Birgunj, Biratnagar, Butwal, Nepalgunj and the agricultural belt between them — everyday land transactions happen in kattha. One Nepali kattha is 3,645 square feet (about 338.6 m²), one-twentieth of a Terai bigha, and itself divided into 20 dhur of 182.25 sq ft each.

A kattha is a practical house-plot size: roughly 60 ft × 60 ft if square. Residential land in Terai towns is typically quoted per kattha or per dhur, so converting to square feet is the natural first step when comparing against builder rates. Note that the same word is used across the border — but a Bihar kattha is only about 1,361 sq ft, well under half the Nepali figure, so a cross-border comparison must never assume the units match.

The formula

Square feet = Kattha × 3,645 (Nepal Terai)

Square feet = Dhur × 182.25

Combined: sq ft = (Bigha × 72,900) + (Kattha × 3,645) + (Dhur × 182.25)

Reverse: Kattha = Square feet ÷ 3,645

Worked examples

Example 1 — a 2 kattha plot in Butwal

2 kattha × 3,645 = 7,290 sq ft. If comparable plots sell at NPR 25 lakh per kattha, the asking price should be near NPR 50 lakh — and now you can sanity-check the per-square-foot rate (≈ NPR 686/sq ft) against town norms.

Example 2 — reading 1-5-10 on a Terai record

A record of 1 bigha, 5 kattha, 10 dhur equals (1 × 72,900) + (5 × 3,645) + (10 × 182.25) = 92,947.5 sq ft, or about 2.13 acres. Our converter accepts the combined bigha-kattha-dhur entry directly.

Good to know

The kattha (also spelled katha or cottah) varies sharply by region: about 3,645 sq ft in the Nepal Terai, about 1,361 sq ft in Bihar, and about 720 sq ft (1 chatak = 45 sq ft × 16) in Kolkata usage, where 20 cottah make the 14,400 sq ft Bengal bigha.
