Volume & Liquid Converters

Convert gallons to liters, cups to mL, fluid ounces to milliliters, tablespoons to teaspoons, and 25+ volume units for cooking, science, and everyday use.

Volume conversions are tricky because the same word means different things — a US cup isn't a UK cup, and a fluid ounce isn't a weight ounce. Each tool below handles these distinctions precisely, covering cooking volumes (cups, tablespoons, teaspoons), liquid measures (gallons, liters, mL), and scientific units (cubic centimeters, cubic feet).
