What this tool does
Convert volume between us gallons, liters, us fluid ounces, milliliters, us cups, cubic feet, cubic yards, cords (firewood), hogsheads (us), ccf (100 cubic feet), board feet, drops. Gallon, cup and fluid ounce are US customary liquid units; imperial UK volumes differ. A cord is 128 cubic feet of stacked firewood, a US hogshead 63 US gallons, a CCF 100 cubic feet (a gas/water billing unit) and a board foot 144 cubic inches. Drops use the conventional 0.05 mL per drop (20 drops = 1 mL); real drop size varies with the liquid and dropper.
