What is the Volume Converter?
Convert any volume unit to all others at once — mL, L, tsp, tbsp, fl oz, cup, qt, gal. Volume conversions help with recipes, fuel, beverages, aquariums and laboratory work. US customary units are used here. Every conversion uses the exact internationally defined factor, so results are precise to 12 significant digits.
