OZ to Cups Converter

About OZ to Cups Converter

Recipes from different countries and different sources use different volume measurement conventions — American recipes lean heavily on cups, tablespoons, and teaspoons, while recipes from metric countries use milliliters and liters, making conversion a routine necessity when cooking from an international recipe or scaling a recipe using a different measuring tool than what you have on hand.

This tool converts between the nine volume units that actually show up in recipes: teaspoons, tablespoons, fluid ounces, cups, pints, quarts, and gallons (US customary), alongside milliliters and liters (metric) — a focused unit list scoped specifically to cooking, unlike the broader general Volume Converter which also includes cubic meters and Imperial gallons less relevant to a kitchen.

All conversions use precise US customary definitions (1 US teaspoon = 4.92892159375 ml, 1 US cup = 236.5882365 ml, and so on) — the standard convention assumed by most American recipes and measuring cup sets, though it's worth noting that some countries define "cup" slightly differently (an Australian cup, for instance, is 250 ml exactly, distinct from the US cup used here).

This is useful for converting an American recipe's cup and tablespoon measurements into milliliters for a metric measuring set, scaling a recipe up or down using a different-sized measuring tool, or understanding a recipe's ingredient quantities when following along from a source using unfamiliar units.

How it works

1. Enter a measurement and select its unit. Any of the nine common cooking volume units.
2. Select the target unit. Or use the swap button to reverse direction.
3. View the exact converted result. Plus the value in every other supported unit at once.
