The conversion is accurate for liquids based on US standards where 1 cup equals 8 fluid ounces. For dry ingredients, weight-to-volume conversions may vary depending on ingredient density, so precision may differ slightly.

Can I use this conversion for dry ingredients like flour or sugar?

Dry ingredients often have different densities, so dividing ounces by 8 provides an approximate volume. For precise baking, it’s better to use specific conversion charts for each dry ingredient, since their cup equivalents can vary.

Why does my recipe call for ounces instead of cups?

Ounces provide a more precise measurement for ingredients, especially in professional cooking or baking. Using weight (ounces) ensures consistency regardless of ingredient packing or moisture content, whereas cups measure volume which can vary.
