About this calculator
Recipes treat produce by count ("1 medium onion") or yield ("1 cup chopped onion") — but they're different units. A medium onion yields ~1 cup chopped, a large yields ~1¾. Citrus yields vary 30% by season — buy 1 extra lemon if a recipe calls for "juice of 3." This converter gives standard yields from established sources (USDA, BHG, America's Test Kitchen). Use as a shopping guide rather than a precise measure.
Frequently asked
How big is a "medium" onion?+
~3 inches across, ~6 oz / 170 g. Large = 4 inches, ~10 oz. Small = 2 inches, ~3 oz.
Why do citrus yields vary?+
Thin-skinned, juicy lemons yield 4 tbsp; thick-skinned dry ones yield 2 tbsp. Roll firmly on counter before juicing — increases yield 20-30%.
Do these vary by region?+
Yes — UK/EU "medium" produce is often smaller than US. The yields here are USDA-standard.
How accurate is "1 clove garlic = 1 tsp"?+
±30%. Cloves vary 2-5g. Buy by weight if you need precision; 30g garlic ≈ 7-10 cloves typical.
What about packaged produce?+
Pre-chopped onion in bags is consistent. 1 cup = 160g for any "medium-dice" white onion.
