The weight of a volume of water have the right to be found provided the thickness, which is the mass compared to the volume. The density of water is 1 kilogram per liter (kg/L) at 39.2°.

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

In common US actions, one gallon of water weighs 8.345 pounds.

The thickness of water varies slightly at various temperatures which will certainly influence the weight of for the same volume.

How to Calculate the Weight of Water

To uncover the weight of water, begin by finding the density(1 kg/L at 39.2°) and the volume of water. Convert the volume of water to liters and then multiply by the density to uncover the weight. Use our volume convariation calculators to transform different quantities to liters.


Example: For 10 mL of water at a density of 1 kg/L

volume = 10 mLvolume = 10 mL ÷ 1000 = .01 Lthickness = 1 kg/Lweight = .01 kgweight = .01 kg × 1000 = 10 g


1 gram is equal to 0.035274 ounces so to acquire an outcome in ounces ssuggest multiply the grams by 0.035274. You deserve to also use our weight convariation calculators to convert from grams and kilograms to pounds and also ounces.
