How Much Does Water Weigh?
The weight of a volume of water can be found given the density, which is the mass compared to the volume. The density of water is 1 kilogram per liter (kg/L) at 39.2°. This means that 1 liter (L) of water weighs 1 kilogram (kg) and 1 milliliter (mL) of water weighs 1 gram (g).
The density of water will vary slightly at different temperatures which will impact the weight of a volume of water.
How to Calculate the Weight of Water
To find the weight of water, start 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 find the weight. Use our fluid volume conversion calculators to convert different volumes to liters.
volume = 10mL
volume = 10mL ÷ 1000 = .01L
density = 1 kg/L
weight = .01kg
weight = .01kg × 1000 = 10g
1 gram is equal to 0.035274 ounces so to get a result in ounces simply multiply the grams by 0.035274. You can also use our weight conversion calculators to convert from grams and kilograms to pounds and ounces.
