The ounce on this page is the international avoirdupois ounce used for groceries, postal weights and most everyday products in the United States. It is a unit of mass, so the conversion does not change with the material being measured.
The factor is exact, but a practical result usually needs fewer digits. Two or three decimal places work well for kitchen and shipping estimates. Keep more digits when the converted value will be used in another calculation.
Do not use this page for precious metals. Gold and silver are commonly weighed in troy ounces, and one troy ounce is heavier than one avoirdupois ounce.
These examples show the formula with common amounts.
100 ÷ 28.349523125 = 3.5274 oz. Rounded to two decimals, 100 grams is 3.53 ounces.
250 grams is 8.8185 oz, which rounds to 8.82 ounces.
500 grams is 17.637 oz, a little more than one avoirdupois pound.
