Pounds to grams multiplies by 453.59237. A 1 lb pack of butter is 453.6 g; a 3 lb chicken is 1360.8 g. The factor is exact via the 1959 international pound. This conversion bridges US recipe weights and metric scales; for precision baking, carry the full factor rather than the rounded 454 g, which introduces a 0.09 % error that compounds across a multi-ingredient bake.
Fitness and supplement labelling in the US states serving sizes and dumbbell increments in pounds, but ingredient dosing on the manufacturing side happens in grams — a 1 lb protein tub is 453.6 g, a 2.5 lb dumbbell increment is 1,134 g, and a 0.25 lb (4 oz) scoop is 113.4 g. Because the exact factor (453.59237) has a long decimal tail, manufacturing spec sheets round to the nearest gram, which is precise enough for anything short of pharmaceutical dosing.

The international avoirdupois pound (lb) is a unit of mass in the imperial and US customary systems, defined as exactly 0.45359237 kilograms since the 1959 international yard and pound agreement. It is the everyday unit for body weight, groceries, and shipping in the United States. Sixteen ounces make one pound; fourteen pounds make one stone in British usage.
The gram (g) is a metric unit of mass equal to one-thousandth of a kilogram. It is the everyday unit for food labeling, postage, jewelry, and laboratory measurements. The 2019 SI redefinition fixed the kilogram (and therefore the gram) in terms of Planck's constant, ending more than a century of dependence on a physical prototype.
