      How much water, by weight, is in an empty cup? Round to the nearest amount an average 17th century merchant could identify.

      I guess in terms of an actual weightless object… Not… But if you have 2 equal weight items, call their combined weight 1 weight unit, take one away, that’s half a weight unit, take two away, that’s zero weight units.
