Grams to Ounces for Cooking: Easy Conversion Chart

June 6, 2025 • 4 min read

Following a recipe from a different country often means dealing with unfamiliar measurements. European and Australian recipes use grams, while American recipes typically use ounces. Here is how to convert between them without ruining your dish.

The Basic Formula

For quick kitchen estimates, remember that 30 grams is roughly 1 ounce. This is close enough for most cooking purposes.

Quick Conversion Chart for Common Weights

• ▶ 25 g = 0.9 oz (roughly 1 oz)
• ▶ 50 g = 1.8 oz (roughly 2 oz)
• ▶ 100 g = 3.5 oz
• ▶ 150 g = 5.3 oz
• ▶ 200 g = 7.1 oz
• ▶ 250 g = 8.8 oz
• ▶ 500 g = 17.6 oz (roughly 1.1 lbs)

Common Ingredient Weights

Different ingredients have different densities, so a cup of flour does not weigh the same as a cup of sugar. Here are approximate weights for common baking ingredients:

• ▶ All-purpose flour: 1 cup = 125 g = 4.4 oz
• ▶ Granulated sugar: 1 cup = 200 g = 7.1 oz
• ▶ Butter: 1 stick = 113 g = 4 oz
• ▶ Brown sugar (packed): 1 cup = 220 g = 7.8 oz
• ▶ Cocoa powder: 1 cup = 85 g = 3 oz
• ▶ Rolled oats: 1 cup = 90 g = 3.2 oz

Tips for Accurate Kitchen Measurements

• ▶ Invest in a digital kitchen scale — they are inexpensive and far more accurate than measuring cups
• ▶ Tare your bowl — zero out the scale with the empty bowl on it before adding ingredients
• ▶ Weigh dry ingredients for baking since precise ratios matter for chemistry
• ▶ Round to the nearest 5g for cooking (not baking) since small differences rarely matter

Why Grams Are Better for Baking

Professional bakers worldwide prefer grams because weight is absolute. A cup of flour can vary by up to 30% depending on how it is scooped, but 125 grams is always 125 grams. If you want consistent results, weigh your ingredients rather than measuring by volume.
