Used a couple of US recipes recently and most of the ingredients are in cups, or spoons, not by weight. This is a nightmare to convert. Do Americans not own scales or something? What’s the reason for measuring everything by volume?

Joke aside, scales on earth measure force and show mass on the assumption of the gravitational pull on earth. On a moon colony, you’d use measuring scales with a different value for the gravitational pull, and get the same values for mass as on earth.
Edit: Also, if anyone finds this stuff interesting to think about. You can measure mass without any force of gravity, but having the measuring device accelerate (e.g. shake) the stuff you want to measure. From “F=ma”, knowing F and a, you get m.
