456 grams to pounds

456 g ≈ 1.005 lbs

Divide the gram value by 453.59237, the exact mass of the international avoirdupois pound. So 456 g ÷ 453.59237 ≈ 1.005 pounds.

Multiply by 453.59237: 1.005 lb × 453.59237 ≈ 455.86 g. The inverse step is the standard way to verify a label that quotes both units.

The international avoirdupois pound has been exactly 0.45359237 kg since the 1959 agreement and is the same in the US and the UK, so 456 g is about 1.005 pounds on either side of the Atlantic. The troy pound (373.2417216 g) is used only for precious metals and gives a different figure.
