Worked examples
An 8 oz steak on a menu
8 oz × 28.34952313 = 226.7962 g
8 ounces = 226.7962 grams. About 227 g. Menu weights are usually for raw meat, so the cooked steak on your plate will weigh less.
One US stick of butter (4 oz)
4 oz × 28.34952313 = 113.3981 g
4 ounces = 113.3981 grams. About 113 g. Many American cake recipes call for one or two sticks, so this is the number to weigh out in a metric kitchen.
Converting ounces to grams in real life
American recipes, restaurant menus and nutrition labels often give weights in ounces. If your scales show grams, multiply before you start weighing. Steaks are a common example: an “8 oz steak” on a menu is about 227 g of raw meat.
In baking, US recipes often list butter in sticks. One stick is 4 oz, which is about 113 g, so two sticks is roughly 227 g.
Make sure the recipe means weight. If it says “fl oz” or the ingredient is a liquid poured into a jug, it is a fluid ounce, which measures volume. Use oz to ml for that. The ounce here is the avoirdupois ounce, 1/16 of a pound. Gold and silver use the heavier troy ounce of 31.1035 g.
