The answer depends upon the type of flour you're using. Unless you have a kitchen scale, you may need weight and volume conversions. Check our handy charts to find commonly used ingredients.

For most home cooks, an extra ounce or two of an ingredient won't make much of a difference. Once you start working with larger quantities, however, precision counts: an incorrect measurement can throw off a ratio and ruin a recipe. Proper ingredient measurements are especially important in baking.
