I bought 175 g pack of salami which had 162 g of salami as well.

    Eight grams off? That seems rather significant. I mean we use to buy 20 grams of weed we’d know if it was almost half shy.

      8g sure but this is only within 2% error. most scales would probably be within 3% so this isn’t surprising

      You would presumably use a higher precision scale for that purpose. I know my kitchen has a large scale that’s only 1 g precision but can go up to 8 kg, and one that’s .01g precision but only goes up to 500g.

      Unless you were using a certified scale and checking it with certified check weights every time you used it, you were just guessing and hoping your dealer wasn’t randomly or purposely off. And density of the material weighed matters also. Weed is far less dense than pasta so a discrepancy can be more noticeable since it takes a larger volume of weed to reach a particular weight than pasta does.

      Understand that a digital kitchen scale is made with the cheapest load sensors a manufacturer is willing to pay for. Nor do they come with any kind of traceable certification as to accuracy class. In fact you get no guarantee that your shiny new kitchen scale is fit for even that purpose - just that it turns on, lights up, and displays something when you place a load upon it.

      Accuracy is a cruel and VERY expensive mistress to chase. And most people don’t understand it anyway.

      that’s why you don’t use a scale that’s only accurate to the full gram (and barely that) when dealing with something where the cost is such that a missing half gram actually makes a difference.
