Converting Recipes from US Customary to Metric Weights
Baking is a science of ratios. When following American recipes with a digital scale calibrated in grams, converting ingredients by weight rather than cups ensures foolproof results. Here are the most essential baking and culinary guidelines:
Butter & Fats
In the US, 1 stick of butter is ¼ lb (4 oz) = 113.4 g. A full 1-pound box contains 4 sticks = 453.6 g. If a recipe asks for 1 cup of butter, use 2 sticks = 226.8 g.
Flour & Dry Grains
A standard 5 lb bag of all-purpose flour weighs 2,268 grams (2.27 kg). One US cup of flour is roughly 120–125 grams, so a 5 lb bag provides roughly 18–19 cups of flour.
Meat, Poultry & Roasts
Roasting timing is often given per pound (e.g., 20 mins per lb). Knowing that 1 lb = 454 g helps you calculate exact cooking times on meat labeled in grams or kilograms. For heavy cuts, refer to our Pounds to Kilograms Converter.
