    If you want to get technical, aren’t grams a measure of mass, not weight, so a kitchen scale needs to assume a value for gravity’s acceleration to tell you grams, which could be slightly off depending where you are on earth?

      I thought that you were on to something and did a quick google search: the variation is apparently only 0.5%. And a variation that big is only found when comparing a measurement on the poles (heavier) vs the equator (lighter) and I think it unlikely that this pasta was made on Antarctica. So nope, it’s not the reason, they really do owe the op 2 grams of pasta.

        Volume is not mass, and neither of them is weight. A gram is strictly speaking a measure of mass, and we just consider it to be a unit of weight in casual terms because the only frame of reference the vast majority of us have has reasonably constant gravity so we conflate mass and weight. That you can sort of use grams to measure volume is literally only because the density of common stuff (especially water) is close enough for most purposes. It’s kinda like measuring a distance in units of time so long as the method of travel is known. I can say “an hour’s walk” and I’m not really measuring distance there but you know roughly how far I mean

          exactly, youre technically correct, but functionally irrelevant in this context
