Free Land Measurement

Land Measuring Tool

Enter sides AB, BC, CD, DA and (optionally) diagonal AC. If AC is empty, the area uses the average method. If AC is provided, the area uses the two‑triangle method (Heron's formula on ABC and ACD).

1 Bigha = 72,900 sq ft • 1 Kattha = 3,645 • 1 Dhur = 182.25 • 1 Kanawa = 11.390625 • 1 Bigha = 20 Kattha • 1 Kattha = 20 Dhur • 1 Dhur = 16 Kanawa

Nepal (Hill)

1 Ropani = 5,476 sq ft • 1 Aana = 342.25 • 1 Paisa = 85.5625 • 1 Dam = 21.390625 • 1 Ropani = 16 Aana • 1 Aana = 4 Paisa • 1 Paisa = 4 Dam

Notes

• Enter sides around the boundary in order: AB, BC, CD, DA. AC is the diagonal between A and C.
• If AC is empty: average method ((AB+CD)/2 × (BC+DA)/2).
• If AC is given: two‑triangle method (Heron's formula) on ABC and ACD; if invalid, tool falls back to average method.
