Standard English means ... being understood world wide.

Basic English was an interesting effort along these lines, and apparently still survives in some forms. Unfortunately, any language standardization effort (update: and Basic English was, I think, primarily intended as a teaching tool) is up against the fact that all languages continually evolve. So we may all be talking about "lakhs of this-and-that" in ten or twenty years. (And it occurs to me to wonder about the relationship, if any, between the words "lakh" and "lot", as in "lots of something." Hmm... Something else to look up...)
