About converting ounces to grams
Ounces to grams is the conversion that lets US recipes and imperial product weights be measured on a metric kitchen scale.
Since one ounce is 28.349523 grams, converting ounces to grams means multiplying by about 28.35. A 4 oz burger patty is 113.4 g, an 8 oz cup of flour is roughly 227 g, and a 16 oz (one pound) bag is 453.6 g.
Digital kitchen scales make this conversion almost obsolete in practice — most switch between grams and ounces at the touch of a button — but the math still matters when a recipe lists one unit and your scale is set to the other, or when scaling a recipe up or down.
- Quick estimate: multiply ounces by 28, then add a touch.
- 16 oz = 1 pound = 453.6 g is a useful anchor for grocery quantities.
