Using large numbers

The numbering system has reached trillions and centillion (which is 10^303).
In India we dont follow millions & billions, instead we go for lakhs and crores. However, we are for left behind without words for larger numbers. Already politicians had crossed thousand crore scams and more. It is time to coin words.

Instead of inventing new words, we can go through the Ancient words and see if they can be re-used, just like lakhs and crores.

Here are the words from Ancient India.
10 ^ 0      eAkam
10 ^ 1      dasha
10 ^ 2      shatham
10 ^ 3      sahasram
10 ^ 4      ayutham
10 ^ 5      laksham
10 ^ 6      niyutham
10 ^ 7      koti           <- this is the crore stuff
10 ^ 8      arbudham
10 ^ 9      vrundham
10 ^ 10     karva
10 ^ 11     nikarva
10 ^ 12     shanga           <- trillion
10 ^ 13     pathrama
10 ^ 14     sAgara
10 ^ 15     anthyam        <- quadrillion
10 ^ 16     mathyam
10 ^ 17     parArdham

These numeric words are preserved in a sanskrit poem.
