Reasonably scaled measurements are very useful, though. Everything in astronomy is measured in scaled units. Mass is in solar masses, interstellar distances are in parsecs (well kiloparsecs) or light years, planetary orbits are in astronomical units. Similar, a lot of atomic physics uses angstroms. Of course, that doesn't apply much when the difference is only a factor of 2, like the pound/kilogram difference, but even there people cheat a bit by just saying "kilo."
