In spanish (at least in es-ES), billion is a million million, which is really annoying when you see clear translation errors. Often, a reporter will read a billion here or there in an english source, and leave it as is, bringing an order of magnitud error into the translated news article. This is especially annoying when that error makes its way into other opinion pieces comparing budgets in the billions and trillions where the author is completely oblivious to the fact that they're mistaken because of a translation error upstream.
