Why people convert Kattha to Aana

Kattha and Aana are the closest like-for-like pair in Nepali land measurement: each is the practical unit for an ordinary residential plot in its own region. That makes this the most meaningful comparison between a Terai town plot and a Kathmandu one, and unlike Bigha-to-Ropani the two are close enough in scale that the resulting number is small and easy to reason about.
