How the Unit Converter works

One gram is exactly 0.0352739619 ounces. That is a definition rather than a measurement: the imperial and US customary units were fixed against metric ones by the 1959 international yard and pound agreement, so this factor does not drift and will not be revised.

Worked through: 100 g x 0.0352739619 = 3.5274 oz.

Going the other way, one ounce is 28.34952313 grams.

To convert without a calculator, multiply by 0.03527. Rounding that to 0.035 is within 0.78% for most purposes.

Cooking, almost always. European recipes weigh ingredients in grams and American ones measure by volume in cups, which is why this conversion gets searched and why weighing is the more reliable method: a cup of flour varies by up to 20% depending on how it was filled.

Precision is worth matching to the input. A measurement given as 1 g carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
