A cubit Yeah, that is a unit that is not only not an international system, it is as far as I know an archaic and poorly defined unit that is not currently in use anywhere. Technically, the question is poorly worded because we are asked to compare a unit with a system of units. Since no system of units consists of just one unit, the answer to the question is any unit of measurement (including one that is part of the international system of units) is not the international system of units. So if the questioner is asking for a currently used system of units that is other than the international system, there are probably many such systems. Any system other than the metric system will do. The one I am familiar with is the English system, also known as the FPS (foot-pound-second) system.
