Convert cups (us legal) to fluid ounces (us) for cooking measurements.
Definition: A US legal cup is defined as exactly 240 milliliters.
History/origin: The legal cup exists mainly for US food labeling and regulatory consistency rather than traditional home cooking.
Current use: US legal cups appear on nutrition labels and in some official food packaging contexts.
Definition: The US fluid ounce measures liquid volume rather than weight. One US fl oz is approximately 29.57 mL.
History/origin: Liquid ounces were separated from weight ounces as measuring systems developed, giving US kitchens a volume unit for drinks and recipe liquids.
Current use: Fl oz is common on milk, juice, cream, stock, soda, water bottles, cocktail recipes, measuring cups, and liquid ingredient labels in the United States.
No kitchen scale? You can estimate weights using volume measurements, common reference objects, and ingredient density tables. Here's how to do it accurately enough for most recipes.
Converting ounces to grams and back is a constant need when cooking from recipes that mix US and metric measurements. Here is the exact conversion, a full reference table, and notes on how food packaging uses these units.
How many teaspoons in a tablespoon? How many tablespoons in a cup? Here are the exact equivalents for US cooking volume measurements, with a reference table and practical notes on where these units trip people up.
