No, I was wrong about that. It's still the ratio, but now this ratio is defined as an exact number. Basically grams defined in terms of daltons.
- kragen 4y agoi thought they defined grams in terms of an integer number of atoms of silicon-28, but the mass of a silicon-28 atom in daltons is not an exact number; it's an empirically measured number, because of the binding energy mass defect, and because the dalton is referenced to a different atom, the carbon-12 atom but all in all it's very confusing
