    I’m assuming this is because the concept of absolute zero did not exist when most of these temperature scales were defined, whereas zero distance and zero weight were easily observable

        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.
