Grams to Ounces Converter

Weighing food accurately pays off when you're trying to make groceries go further. Precise weights underpin scaling a recipe up or down, tracking nutrition, and cutting waste. Moving cleanly between grams, ounces, pounds, and kilograms lets you portion ingredients deliberately and stretch what you buy.

The math rests on standard international units. One avoirdupois ounce (oz) is exactly 28.349523125 grams (g), and one pound (lb) is 16 ounces, exactly 453.59237 grams; the calculator rounds these to 28.3495 g and 453.592 g, which makes no practical difference for kitchen amounts. One kilogram (kg) is 1,000 grams. Applying those fixed factors produces accurate figures for cooking, shopping, and any other weighing task.

There's more than one kind of ounce: the troy ounce used for precious metals is 31.1035 grams, about 10% heavier than the avoirdupois ounce used for food, so confirm which one a figure refers to. Rounding partway through a multi-step conversion is another trap, since small errors compound and can throw off a baked recipe noticeably. It also helps to keep weight and volume separate, because a fluid ounce measures volume while an ounce here measures mass, and they are not interchangeable.
