    Plenty of people have already explained that consumer scales show bullshit. But there’s another reason why your weight is not the same as producer’s weight.

    You see, kilograms are a unit of measure of mass, not weight. Weight is measured in Newtons. And 1kg = 1 * g Newtons. But here’s the catch - g is not constant in real life. It changes from 9.7639 to 9.8337 depending on your location. That’s almost 1% of variance.

    What that means is that if you take your scales and your pasta and go on a worldwide trip, then you will see different weight in different locations.
