Teaspoons Tablespoons cups Pints Quarts Gallons Milliliters Liters Cubic customs Cubic Feet Cubic Yards Cubic Centimeters Cubic meters
The weight of a volume of water can be found given the density, i m sorry is the mass contrasted to the volume. The density of water is 1 kilogram per liter (kg/L) in ~ 39.2°.

This means that 1 liter (L) of water weighs 1 kilogram (kg) and also 1 milliliter (mL) the water weighs 1 gram (g).

In usual US measures, one gallon that water weighs 8.345 pounds.


*

The thickness of water different slightly at various temperatures which will affect the weight of for the same volume.

How to calculate the weight of Water

To discover the load of water, begin by detect the density(1 kg/L in ~ 39.2°) and the volume of water. Convert the volume that water to liters and also then main point by the density to discover the weight. Use our volume conversion calculators to convert different quantities to liters.


Example: for 10 mL that water in ~ a density of 1 kg/L

volume = 10 mLvolume = 10 mL ÷ 1000 = .01 Ldensity = 1 kg/Lweight = .01 kgweight = .01 kg × 1000 = 10 g
1 gram is same to 0.035274 ounces so to gain a an outcome in ounces just multiply the grams by 0.035274. You can additionally use our weight conversion calculators to convert from grams and kilograms to pounds and ounces.

The Temperature influence the load of Water

As we stated briefly above, temperature has actually an effect on the density of water, and also thus its an accurate weight will vary through the temperature. As the temperature that water rises, it expands, resulting in it to boost in volume slightly.<1>

At a molecular level, as the temperature rises, the heat of the water molecules increases, which increases their energy. Together the power in the molecules rises, the particles within move and also vibrate more, leading to them to take it up an ext space.

Thus, the warmer the water is, the an ext volume it will certainly consume, and also the lower its thickness will be. The chart below shows the thickness of water at assorted temperatures, follow to the united state Department the the Interior.<2>
