The ounces to grams formula
Multiply ounces by 28.3495 to get grams: g = oz × 28.3495. So a 4 oz portion is 4 × 28.3495 ≈ 113 g, and 8 oz is 227 g. For mental math, 1 oz ≈ 28 g and 16 oz (one pound) ≈ 454 g.
Recipes across the Atlantic
American recipes weigh in ounces and pounds; most of the world cooks in grams. 2 oz of sugar is 57 g, a 6 oz steak is 170 g, and a 12 oz bag of chocolate chips is 340 g. Watch for fluid ounces (fl oz) — those measure volume and need a density, not this converter.
