Method and sourceoz to g Conversion Formula
To convert ounces to grams, multiply the ounce value by 28.3495. This factor comes from the international avoirdupois ounce, which is defined as exactly 28.349523125 grams.
Ounces and Grams Explained
Ounces (oz)
An ounce (oz) is the fine-weight unit of the US customary and imperial systems, defined as exactly 28.349523125 g — roughly the weight of a slice of bread or three $1 coins. Sixteen ounces make one pound, so the ounce covers the space where pounds are too coarse: shaved ham at the deli, espresso doses, snack packs, and airmail letters to relatives overseas all live between a fraction of an ounce and about 16 oz.
Where it is used: Ounces dominate packaged-food labels, postal rates, and kitchen recipes in the United States, and they still pop up in older Australian cookbooks, family recipe cards, and on British packaging.
Origin: The ounce descends from the Roman uncia, one twelfth of a libra. The avoirdupois ounce was fixed internationally in 1959 at exactly 28.349523125 grams.
Grams (g)
A gram (g) is the base building block of metric mass, equal to one thousandth of a kilogram. It sits on the scale of everyday precision: a paperclip weighs about 1 g, a $1 coin 9 g, and a family block of chocolate around 180 g. Nutrition panels, pharmacy balances, and spice measures quote grams directly, and because the metric system moves in tens, converting grams to kilograms or milligrams is just a decimal shift.
Where it is used: Grams are the universal unit for kitchen scales, nutrition labels, laboratory work, and supermarket packaging across Australia and every other metric country — that is, nearly the entire world.
Origin: The gram was defined in 1795 as the mass of one cubic centimeter of melting ice water, one of the two founding units of the metric system alongside the meter.

Expert Tips for oz to g Conversion
Remember four anchors and interpolate the rest: 1 oz = 28.35 g, 4 oz = 113.4 g, 8 oz = 226.8 g, and 16 oz = 453.592 g. Most recipe amounts fall between them.
Butter blocks differ by market: a US stick is 4 oz (113.398 g), while an Australian block is 250 g (8.82 oz). Converting before substituting keeps your biscuits and slices from turning out greasy or dry.
Restaurant protein portions track ounces on US menus — 3 oz = 85 g, 6 oz = 170.1 g, 8 oz = 226.8 g. Aussie butchers and steakhouses work in grams, so a 6 oz fillet is simply a 170 g cut.
Maternity wards weigh babies in grams, but the grandparents often ask in pounds and ounces — a 3.402 kg newborn is 7 lb 8 oz, and the 8 oz component works out to 226.796 g.
Australia Post charges letters by the gram (a small letter can weigh up to 125 g), but US postage jumps by the ounce. A 1.5 oz letter is 42.5 g, and knowing the 28.3495 factor tells you exactly which US price bracket it lands in.
