A unit never comes alone; it always follows a number. A variable never follows a number without an operator in between. (Ok, there's the math shortcut of "6 A" that could mean "six times the variable A", but usually the context makes clear what is meant, and if not, you can make the implied multiplication operator explicit.) Also normally I either work in variables (on the right side) or in numbers; rarely mixed.
