About the Volume Converter

Recipes mix millilitres with cups, fuel comes in gallons or litres, and medicine doses in teaspoons — volume units are everywhere and rarely consistent. This converter handles the full set from cubic metres down to teaspoons, US customary throughout (the cups in most published recipes), updating all measures from one input. The kitchen panel puts cups, tablespoons and teaspoons side by side for recipe scaling.
