About Gallon (US) (gal)
A US customary unit of volume equal to exactly 3.785411784 liters, or 128 fluid ounces. US gallons are the default unit for US gasoline pricing and fuel economy (miles per gallon), milk and beverage containers, water heaters, and pool/aquarium capacity. Different from the Imperial gallon used in the UK (4.546 L) — a frequent source of confusion when comparing US vs. UK fuel economy or trans-Atlantic recipes. One US gallon weighs about 8.34 pounds.
About Milliliter (mL)
A metric unit of volume equal to one thousandth of a liter (0.001 L) or exactly one cubic centimeter. Milliliters are the everyday metric unit for medicine dosing, cooking measurements outside the US, laboratory chemistry, perfume and beverage cans. A standard medical syringe is 10 mL; a shot glass is about 44 mL; a standard intravenous saline bag is 500 or 1,000 mL. In chemistry and pharmacy, mL and cc (cubic centimeters) are used interchangeably.
