Before you rely on it
The everyday pound, and the 454 g on packets
This page uses the avoirdupois pound — the pound on a kitchen scale, a meat label or a parcel. Since 1959 it has been defined as exactly 453.59237 grams, so every answer here is exact before rounding.
Food labels round it: "1 lb (454 g)" is the same pound written to the nearest gram, not a different unit.
A 500 g pack is not a pound. It is about 10 percent heavier, which matters when a recipe written in pounds meets metric packaging.
Gold and silver use the troy pound, about 373 g, which this page does not convert.
