Tips
UK recipe books published before the 1980s often use imperial weights (oz/lb). Use this converter when following older recipes.
When scaling between US and UK recipes, note that the US often uses cups and sticks while the UK uses grams. Convert oz to grams for consistency.
For kitchen scales, switch to grams for more precise measurements — 1g increments are more accurate than 0.1 oz increments on most scales.
About this oz to grams tool
Ounces and grams are both units of weight used in cooking, but different countries favour different systems. US recipes commonly use ounces and pounds; UK and European recipes increasingly use grams. The conversion is straightforward: 1 oz = 28.35g, or approximately 28g for quick mental arithmetic.
This converter is designed for cooking contexts where you need to convert between imperial and metric weights. Common kitchen quantities like 4 oz (113g), 8 oz (227g), and 16 oz/1 lb (454g) appear frequently in recipes for meat, fish, butter, and chocolate. Knowing these benchmarks by heart saves time mid-recipe.
Note that the ounce used in cooking is the avoirdupois ounce (28.35g). This is different from the troy ounce (31.1g) used for precious metals — you will never encounter the troy ounce in a recipe. The fluid ounce is also different: it measures volume, not weight, and equals approximately 29.57ml (US) or 28.41ml (UK).
If you cook from both American and British recipes, a kitchen scale set to grams is the most versatile tool. Most digital scales switch between oz and grams at the touch of a button. For precise baking, grams are preferable as they eliminate ambiguity around cup packing and measuring technique.
