T. N. Ninan, writing in Business Standard, calls for a shift away from lakh and crore to thousand, million, billion and trillion. We agree! And we've moved our Indian Business Cycle page to metric.
Indian economics is easier in the metric system. GDP is Rs.55 trillion. The market capitalisation of Reliance is Rs.3.5 trillion. On a good day, Nifty as an underlying has derivatives turnover of Rs.1.5 trillion. A billion dollars is Rs.44 billion. When I was at the MoF, I had tried suggesting that the budget documents should be switched to metric, without success.
