When you need bigha in ropani

The bigha belongs to the Terai and the ropani to the hills and the Kathmandu Valley, so this is the conversion for comparing land across the two: a family holding in the Terai against a house plot in the valley, or a price per kattha against a price per aana. It matters when family land is divided too, if one share sits in the Terai and another in the hills and a fair split needs both in the same unit.

A bigha is 72,900 sq ft, the area of a square 270 ft on a side, and a ropani is 5,476 sq ft, a square 74 ft on a side. So 1 bigha = 13.3126 ropani, about 13⅓, written 13-5-0-0.04 in R-A-P-D. The smaller units: 1 kattha is 0.6656 ropani (0-10-2-2.4), and 1 dhur is 0.5325 aana.

Going the other way, divide ropani by 13.3126. A 1-ropani plot is 0.07512 bigha, which a Terai lalpurja would write as 0-1-10.05: one kattha and about ten dhur.

Worked example: 2.5 bigha

2.5 × 72,900 = 182,250 sq ft. Divide by 5,476 for 33.28 ropani. In R-A-P-D that is 33-4-2-0.09, and in B-K-D the same land is 2-10-0.

Common mistakes

Swapping kattha for aana. 1 kattha is 10.65 aana, so 5 kattha is 53.25 aana (3-5-1-0.01), not 5 aana.
Using 13 ropani a bigha. It leaves out 5 aana on every bigha, more than a 4-aana house plot.
Multiplying when you should divide. Ropani to bigha is ÷ 13.31; multiplying turns 2 ropani into 26.63 bigha instead of 0.1502.
Assuming every bigha is Nepal's. The bigha used in India varies from state to state; this page uses Nepal's standard 72,900 sq ft bigha.
