How much does one liter of water weigh?

Answer 1

1 kilogram (2.205 lbs.) at 4 °COne liter is composed of 1,000 cubic centimeters (cc) . One cc, which is also the same as a milliliter (mL) of water weighs one gram. Therefore, a liter of water weighs one kilogram.

At different temperatures, the density of water is slightly different. At any other temperature than 4 °C, the density of water is in fact lower (yes, water is most dense at 4 °C!). However, the change is very small at most temperatures, and so to a very close approximation, the weight of 1 liter of water is 1 kg at most temperatures.

See the Related Questions to the left for more information about how the density of water changes with temperature.

liter is a unit of volume not of weight.

A liter of water weighs much more than a liter of air.

The answer is 1 kg
