Morphology
The phrase 'constant quantity' is directly compositional: a 'quantity' (a measurable amount) described by 'constant' (not changing or fixed), so the meaning 'a quantity whose value does not change' follows immediately from the parts. This pattern is straightforward and cross-linguistically common, so an average B1 learner who knows both constituents will understand it.
Etymology
Constant quantity comes from a simple image: constant means 'always the same' and quantity means 'amount'. So think of a jar that always has the same number of coins; that picture explains why constant quantity means 'a quantity that does not change'.
