How many ounces is 100 grams in cooking?

100 grams equals 3.527 ounces, or about 3 1/2 oz. This is a common measurement for flour, sugar, and chocolate chips in baking recipes.

How many grams is 1 ounce of flour?

One ounce of flour is approximately 28.35 grams. However, the actual weight depends on how the flour is measured (scooped vs. spooned into a cup), so a scale is more reliable.

What does "1/4 oz" mean in a recipe?

One-quarter ounce equals about 7.09 grams. US recipes often express small amounts in fractional ounces, especially for spices, yeast, and leaveners.

Are cooking ounces and regular ounces the same?

Yes. Cooking recipes use avoirdupois ounces (28.349523125 g), the same standard ounce used for general weights. Troy ounces (31.1 g) are only for precious metals and never appear in recipes.

How do I scale a recipe from 4 to 6 servings?

Use the Recipe Scaler section: enter your original servings (4), target servings (6), and the original ingredient weight. The tool multiplies the weight by 6/4 = 1.5 and shows the result in both grams and ounces.

Why do baking recipes use grams instead of cups?

Grams measure actual mass, which is consistent regardless of how densely an ingredient is packed. Cups measure volume, so 1 cup of flour can range from 120 g to 160 g depending on scooping method. Grams give more accurate and repeatable results in baking.
