How many cups of water does it take to equal 6 pounds?

-- 1 cup = 236.588 mL

-- 1 mL of water weighs exactly 1 gram (at 4 °C, but pretty close at most temperatures)
-- 1 lb = 453.5924 grams.


1 lb = 453.5924 grams ÷ 236.588 mL/cup = 1.91722 cups

So 1.917 cups of water weighs 1 pound (or 1 cup weighs 0.5216 pounds)

So six pounds of water would be 11.5033 cups of water. Note that this is answer is for WATER ONLY. Other substances have difference densities, and because a cup is measure of volume, one cup of feathers weighs a different amount than a cup of lead. See the Related Questions for converting from volume to mass.
