# How much does 1 litre of water weigh?

The density of water is 1000 kg/m3 , which is the same as 1

kg/L. So 1 liter of water weighs 1 kg.

Not true because a kilogram is a measure of mass - NOT of

weight. The mass of one litre of water is approx 1 kilogram and ON

THE SURFACE OF THE EARTH it would weigh around 9.8 Newtons. On the

surface of the moon, it would weight around 1.6 Newtons and in

outer space it would be weightless.

Besides, the density of water, at 1 atmosphere has a maximum

value of 999.9720 kg/metre3 - near enough, but not quite 1,000.

### How much liter equals to an gram?

A "litre" can weigh different amounts depending on what the
litre is comprised of. For example, a litre of water will weigh
more than a litre of chocolate mousse (more air in the mousse, but
I admit the example's odd)... If you then dissolve a lot of sugar
in the litre of water, it will weigh more than it did previously
(the volume will also increase a little, some will have to be
poured out to retain "1 litre", but it will not weigh what it did
originally). So it is not possible to know how much of a litre
weighs a gram without knowing what substance the litre is comprised
of.
