About this calculator
Ounce-to-gram conversion is a fixed factor: 1 oz (avoirdupois, the standard in US cooking) = 28.3495 g. Don't confuse with troy ounces (precious metals, 31.103 g) or fluid ounces (volume, ~29.6 mL). For cooking purposes, the avoirdupois ounce is what you want. Typical recipe weights translate cleanly: 8 oz ≈ 227 g, 4 oz ≈ 113 g (a half-stick of butter), 1 lb (16 oz) ≈ 454 g.
