At 4☌, the density of fresh water on Earth is typically assumed to be 1000 kg/m 3.ĭensity is the amount of matter in a certain volume. The grams per milliliter (1 g/ml), grams per cubic centimeter ( g/cm 3), and pounds per cubic foot ( lb/ft 3) are common water quantities. This is the same as 1 gram per milliliter (g/ml) or 1 gram per cubic centimeter (g/cm 3), rounded up.

The Density Of WaterĪt 4.0☌ (39.2☏), the density of water in g/ml is 0.9998395. The weight of 1 liter (l) of pure water (at 4 ☌) is equal to 1 kilogram (kg). The weight of water depends upon the temperature at which it is stored.įor the purposes of answering the question, “How much does a gallon of water weigh?” we will focus on the weight of fresh water at 62 degrees Fahrenheit (17 degrees Celsius).ġ US gallon of water equals 8.345 pounds, which is 3.785 kg (at 17 ☌).ġ imperial gallon of water = 10.02 pounds, or 4.545 kg (at 17 ☌). Unit Weight for Some common Materials Material How Many Bottles Of Water Equal A Gallon?.As a result, one-thousandth of a liter of water, also known as one milliliter (1 mL), has a mass of about 1 g 1000 liters of water has a mass of about 1000 kg (1 tonne or megagram).Īccording to the National Institute of Standards and Technology, a cup of water weighs approximately 224 grams (half a pound).Īccording to the United States Geological Survey, a liter of water weighs about 1 kilogram (2.2 pounds) (USGS).Īccording to the USGS, a gallon of water weighs approximately 3.79 kilograms (8.35 pounds). When measured at its maximum density, which occurs at about 4 degrees Celsius, one liter of water has a mass of almost exactly one kilogram. To find the weight, first, convert the volume of water to liters and then multiply by the density. To determine the weight of water, first, determine its density (1 kg/L at 39.2°) and volume. So, if you don’t have a food scale, knowing how much certain amounts of water weigh can help you ace any meal. Many recipes use weighted ingredients rather than fixed amounts such as tablespoons or cups. When it comes to cooking, water weight is crucial.

Specific gravity is a ratio and has no units.

The specific gravity of water is 1 at 4 degrees Celsius.
