What is the standard : long or short scales

Question

I know about long and short scales of numbering systems, but I want to know, what is the standard naming of large numbers?!! is that back on the long scale or the short scale?!! so if someone in the world say 1 billion, so I've to take it as 10^9 or 10^12?

I came across this Wikipedia link which clarifies some countries/regions that use short scale and some others that use long scale, but this is already not a clear answer to my question.

You've answered your own question:

There is no standard. Unfortunately. Just as how English words and idioms are different depending on where you say it and to whom.
