Water Weight Calculator
How much does water weigh?
The weight of water is directly proportional with its density. The density of water is about 1 kilogram per liter (Kg/liter) at 4 degrees Celsius.
At 4 degrees Celsius water has the lowest volume and the highest density therefore water at this temperature has the highest weight. Water at another temperature, even though the difference is low, has a lower density therefore weighing less.
Our Water Weight Tool calculates the weight of water at room temperature and supports both metric and imperial measurement systems and outputs the following units: ounces, Pounds, Grams and Kilograms.
