1015 = 1 000 000 000 000 000
which is one thousand billion or one billiard on the long scale (as used in Europe)
or one quadrillion on the short scale (as used in USA).
* * * * *
The UK, which IS a part of Europe and the main English speaking one within it, has not used the long scale since the mid 1960s so that part of the answer is misleading.
1,000,000,000,000,000
10 to the 18th power is called Quintrillion
10 to the 15th power i think =]
10
10 to the 15th power is equal to 1000000000000000. This is called 1 quadrillion.
It is ten billion or 10,000,000,000

To determine the power of 10 closest to the actual numerical value of a quantity, you can use logarithms, specifically the base-10 logarithm (log10). By calculating the logarithm of the number, you can identify the exponent that represents the closest power of 10. For example, if log10(x) equals 3.2, the closest power of 10 is 10^3, indicating that the number is roughly in the range of 1,000. Rounding the logarithmic result to the nearest whole number gives you the closest power of 10.
