Converting between the two systems

Some sources say there are 13 ropani in a bigha and others say 13.5. Our calculations suggest about 13.3 ropani to the bigha, and that 1 aana is about 1.88 dhur, which is also in disagreement with certain sources. Perhaps one reason why the subject is so confused is that in reality the conversion is not done. We have found no examples of land measurements in ropani being summed up in a measurement in bigha. The two systems seem to be kept separate.
