One pound also equals 16 ounces, and each ounce works out to about 28.35 grams. In kilograms, a pound is 0.45359237 kg. So when you see 453.59237, it isn't marketing precision, it's the legal definition carried out to five decimals.

One international pound equals exactly 453.59237 grams. That value has not changed since 1959, and every national measurement office still holds to it.
