How this is calculated

Formula:

area_target = area_source

In plain language:

Areas are normalized to square meters. One katha is taken as 720 square feet (≈66.8902 m²), then rescaled into any selected unit.

The formula is always visible so you can verify the math and explain your numbers to anyone who asks.

Katha to square feet, clarified

A katha is a traditional South Asian land unit. The most common modern usage in Bangladesh and West Bengal sets 1 katha = 720 sq ft, which equals ≈66.8902 m². This calculator converts in both directions and surfaces metric context so you can compare survey records or building plans quickly.

How the conversion works

The calculator normalizes everything to square meters, then rescales:

$1\\,\\text{katha} = 720\\,\\text{ft}^2 = 66.8901888\\,\\text{m}^2$
$A_{\\text{katha}} = A_{\\text{m}^2} / 66.8901888$
$A_{\\text{ft}^2} = A_{\\text{m}^2} / 0.09290304$

Units and conversions

Unit	Symbol	Relation to base (m²)
Square meter	m²	base
Hectare	ha	$1\\,\\text{ha} = 10{,}000\\,\\text{m}^2$
Square foot	ft²	$1\\,\\text{ft}^2 = 0.09290304\\,\\text{m}^2$
Square yard	yd²	$1\\,\\text{yd}^2 = 0.83612736\\,\\text{m}^2$
Katha (BD/WB)	katha	$1\\,\\text{katha} = 66.8901888\\,\\text{m}^2$

Worked examples

1 katha → square feet
$1 \\times 720 = 720\\,\\text{ft}^2$ .
2,000 sq ft → katha
$2000 / 720 \\approx 2.78\\,\\text{katha}$ .
5 katha → m²
$5 \\times 66.8901888 \\approx 334.45\\,\\text{m}^2$ .

Tips and pitfalls

Regional definitions vary; this tool uses the 720 sq ft standard. Check local codes before filing paperwork.
Use hectares for quick comparisons on agricultural plots.
Keep areas non‑negative; the solver blocks negative entries.
