How much does Water Weight?
Water weight is not a straight static calculation, as it changes based on environment values like temperature. Temperature affects the density of the water, resulting change of weight. For the same volume of water, Cold water weights more in comparison hotter water weights less.
In general, we calculate the water weight assuming the temperature will be normal room temprature, which is (70°F / 21°C). At room temperature the density of water is 0.99802 g/ml.

Water Density at Various Temperatures
The Temperature Affects the Weight of Water, temperature has an effect on the density of water, and thus its precise weight will vary with the temperature. As the temperature of water rises, it expands, causing it to increase in volume slightly.
At a molecular level, as the temperature rises, the heat of the water molecules increases, which increases their energy. As the energy in the molecules rises, the particles within move and vibrate more, causing them to take up more space.The chart below shows the density of water at various temperatures.

|---|---|
| 32° / 0° | 0.99987 g/cm3 |
