I'm sure glad we're not discussing precious and standard metals where there's two numbers of ounces in a pound; one's got 16 of 'em and the other's got 12.
How 'bout the length of a mile? 2500 yards, 5280 feet, one minute of latitude, 6081 feet or 1760 yards? There's miles with each number for different standards.
