What is 16oz water weight?

Water weighs approximately 8.34 pounds per gallon, so 16 ounces of water weighs 0.5 pounds or approximately 0.227 kilograms. This weight is often used as a benchmark for measuring liquids in the US, as 16 fluid ounces is equivalent to 1 US pint or approximately 473 milliliters. It is important to note that the weight of water can vary slightly depending on the temperature and pressure at which it is measured, but this variation is usually negligible for most everyday purposes.
