oz 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 a 30 g pack of roasted chana. Sixteen ounces make one pound, so the ounce covers the space where pounds are too coarse: cheese slices, espresso doses, snack packs and first-class letters all live between a fraction of an ounce and about 16 oz.
Where it is used: Ounces dominate packaged-food labels, courier rates and recipes in the United States, and they still appear alongside grams on UK packaging and on imported goods sold in Indian gourmet stores and online marketplaces.
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 raisin 0.5 g, and a chocolate bar 45 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, FSSAI nutrition labels, laboratory work and retail packaging across India and every metric country — that is, nearly the entire world.
Origin: The gram was defined in 1795 as the mass of one cubic centimetre of melting ice water, one of the two founding units of the metric system alongside the metre.
