How Much Does A Liter Of Water Weigh? Why? – Online Converter

The short answer to your question how much does a liter of water weigh is 1 KG. The density of water is 1g/cm 3, so 1 liter of water weighs 1 kilogram or 1000 gram, which is equal to 2.2 pounds. 1 liter of water weigh 1.0 kg in US, but it weighs 1.025 kg in UK.

The specific gravity of water is 1.00. One liter of water weighs 1 kilogram. 1 cubic centimeter of water weighs 1 gram. The density of water depends on temperature. The temperature of the water will affect the weight which is why the density differs.

Water weighs less as its temperature increases. One liter of water weighs 1 kilogram at 4 °C (39.2 °F), and this increases at a rate of about 0.54% per degree Celsius, to a maximum of 1.0% at 37 °C (98.6 °F). The 4 °C figure is the average of the highest and lowest temperatures that water can attain, and is used as a reference point by British and American scientists.

Water weight depends on the temperature and the pressure, but at 100 degrees Celsius, a litre of water will weigh 1.000 grams. But at 0 degrees Celsius, it will weigh 1.0 gram. The 20-degree difference means that a litre of water at 0 degrees Celsius weighs 20% less than it does at 100 degrees Celsius.

One litre of salt water weighs more than one litre of pure water because of the extra weight of the salt.
Mass of pure water = 1 kg
Mass of salt water = 1 kg + m * (3.5 grams of salt per kg of water)
Mass of salt water = 1 kg + (3.5 x 1) * m
Mass of salt water = 3.5 kg

Here’s why a liter of water isn’t equal to a liter of ice.

Water molecules are made of two hydrogen atoms and one oxygen atom. Water is a compound and a diatomic molecule and is composed of two hydrogen (H2O) and one oxygen (O) atoms. Water is a polar molecule and is also known as dihydrogen monoxide (DHMO). For water to reach its maximum density, it requires 4 grams per milliliter of water. For water, 6+1+1+1+1+1+1 = 18 H2O molecules weigh 1 g.

So, how much does a litre of water weigh? a liter of water weighs 1 kilogram or 2.2 pound. To convert a liter of water to a different unit of measure, you need to know the density of water. When water is pure, it has a density of one kilogram per liter. If the density of the water is different from one kilogram, then you will need to convert the water into a kilogram.
