What is how much does 16 oz of water weigh?

Sixteen ounces (oz) of water is equivalent to one pound (lb) in weight. This is because, under standard conditions, 1 fluid ounce of water weighs approximately 1 ounce avoirdupois. Therefore, 16 fluid ounces of water, which is commonly referred to as "a pint" in the U.S. customary system, weighs about 16 ounces or 1 pound. This is a useful approximation often used in cooking and everyday scenarios.
