تحويل أونصات السوائل إلى أكواب: الطهي والخبز وقياس المشروبات

In the US customary system, 1 cup equals exactly 8 fluid ounces. This is a fixed relationship: 2 cups = 16 fl oz, 3 cups = 24 fl oz, and so on. To convert cups to fluid ounces, multiply the number of cups by 8. To convert fluid ounces to cups, divide by 8. This 1:8 ratio is the foundation of American recipe measurements and remains constant regardless of what liquid you're measuring.

American recipes use cups because the United States never officially adopted the metric system for everyday cooking. Cups are convenient for home cooks—they're intuitive, require no calculations, and most American kitchens have cup measuring tools. Historically, recipes were developed using cups, and the convention persisted. Professionally, many chefs now use grams and milliliters for precision, but home recipes remain cup-based. International recipes increasingly provide both cup and metric measurements for accessibility.
