As far as I can work out, India does not use either the long or short scales but their own system of numbers (with names based on odd powers of 10, so names for 10 x 1012 and 10 x 1018 exist).
With India being a former part of the British Empire, they can use the [pre-1974] British use of the long scale where a trillion has 18 zeros.
However, in [international] commerce, they may interpret it on the short scale with 12 zeros.
there are 12 zeroes in 1 trillion
There are 12 zeros in 3 trillion.
There are 18 zeros in a quin trillion
There are 13 zeros in 80 trillion.
1 Trillion = 100,000,000,000 eleven zeros
there are 12 zeros. 1.000.000.000.000 is one trillion
100,000,000,000,000 = hundred trillion which has 14 zeros in it
Thousand trillion = 1,000,000,000,000,000 which has 15 zeros in it
1 trillion is 1,000,000,000,000 14.28 trillion is 14,280,000,000,000 There are 10 zeros
There are nine zeros in a billion (1,000,000,000) and twelve zeros in a trillion (1,000,000,000,000).
There are 15 zeros in the number 6,000,000,000,000,000 (6 trillion). ---- Actually, this is six trillion -> 6,000,000,000,000 so there are actually 12 zeros in 6 trillion.
11 zeros
