If you need the result in pounds and ounces rather than decimal pounds:
New Zealand uses the metric system, so food labels, postal weights, and scientific measurements are given in grams and kilograms. However, pounds are still widely understood, particularly in cooking recipes from the United States and United Kingdom, and in body weight discussions where some people use the imperial system.

The value 453.59237 grams per pound is exact by legal definition, not a measured approximation. Before 1959, slightly different values were used in different countries (the US pound was 453.59243 g and the UK pound was 453.59237 g). The 1959 International Yard and Pound Agreement standardised the pound at 453.59237 grams to 8 significant figures, and that value has been in force ever since. The gram itself is defined via the kilogram, which since 2019 is defined by fixing the Planck constant, making the entire chain of definitions exact in SI units.
