Maybe it is a number that you are âcarrying overâ to do a subtraction, or a persuasive argument that you are going to make as soon as the other person finishes talking. Either way, you are using your short-term memory.
The US gallon, which is equal to approximately 3.785 L, is legally defined as 231 cubic inches. A US liquid gallon of water weighs about 8.34 pounds or 3.78 kilograms at 62 Â°F (17 Â°C), making it about 16.6% lighter than the imperial gallon. There are four quarts in a gallon, two pints in a quart and 16 US fluid ounces in a US pint, which makes a US gallon equal to 128 fl. oz.
An approximate weight is 8 pounds, based on the common adage: A pint's a pound the world around. So, since a gallon of liquid is 4 quarts or 8 pints, it's nearly 8 pounds. However water is a bit heavier, since water goes to the bottom, and diesel fuel, gasoline, kerosene stay on top. Answer by selen.
