ISO 31-11/ISO 80000-2?
The question that nobody has asked, is why is this not in the ISO notation. The answer is simple, the ISO standards are not distributed freely. Until I've read the standard, I can't even start to think about supporting it. Supporting it doesn't seem like the right solution either since the wikipedia article only demonstrates it, it does not actually use it, which is a good indicator that the common audience is not familiar with it. -- Strife (talk|contribs) 12:11, 9 February 2011 (PST)
