Quick Reference

1 Ropani = 5,476 sq ft

1 Bigha = 72,900 sq ft

1 Aana = 342.25 sq ft

1 Kattha = 3,645 sq ft

1 Ropani = 16 Aana

1 Bigha = 20 Kattha

1 Aana = 4 Paisa

1 Kattha = 20 Dhur

1 Bigha ≈ 13.31 Ropani

1 Hectare ≈ 19.66 Ropani

Conversion basis: 1 ropani = 5,476 sq ft; 1 bigha = 72,900 sq ft. Metric values use 1 sq ft = 0.09290304 sq m and 1 hectare = 10,000 sq m. Results are rounded for display; use your survey and land records for legal measurements. Metric conversion source

Worked land conversion examples

Convert to square feet first, then divide by the square feet in the target unit. The examples below use the same factors as the calculator; approximate answers are rounded to four decimal places.

1 Ropani to Kattha

5,476 ÷ 3,645 ≈ 1.5023 Kattha

1 Bigha to Ropani

72,900 ÷ 5,476 ≈ 13.3126 Ropani

1 Acre to Ropani

43,560 ÷ 5,476 ≈ 7.9547 Ropani

1 Hectare to Ropani

107,639.1042 ÷ 5,476 ≈ 19.6565 Ropani

Entering an area with more than one unit

The input accepts one number and one unit. Add the parts in a common unit first. For 1 ropani and 4 aana: 1 + 4 ÷ 16 = 1.25 ropani. Enter 1.25 and select Ropani; the area is 6,845 sq ft. Entering 1.4 would mean 1.4 ropani, not 1 ropani and 4 aana.

For 1 kattha and 10 dhur: 1 + 10 ÷ 20 = 1.5 kattha. Enter 1.5 and select Kattha; the area is 5,467.5 sq ft. The mixed-unit result cards and decimal rows describe the same area in different forms, so do not add them together.

Nepal Land Measurement Systems

Nepal uses two traditional land measurement systems. The Hill system (Ropani-Aana-Paisa-Dam) is used in Kathmandu, Pokhara, and the hilly regions. The Terai system (Bigha-Kattha-Dhur) is used in the southern plains. Both are used in official land documents alongside international units.

Hill system: 1 Ropani = 16 Aana = 64 Paisa = 256 Dam = 5,476 sq ft. Terai system: 1 Bigha = 20 Kattha = 400 Dhur = 72,900 sq ft. 1 Bigha ≈ 13.31 Ropani.
