How many grams are there in a liter?

Answer 1

It depends on the density, and what the liquid is.

One liter of water at 4°C will weigh 1000 grams; this is the temperature at which water is densest. If the liquid is alcohol, which is less dense than water, there will be fewer grams in a liter.
A litre is a measure of volume, grams are a measure of mass. Without further information no conversion is possible.
There's 1000 grams in 1kilogram.
And theres 1000 millilitres in 1litre.

Answer 2

One litre of water has a mass of almost exactly one kilogram (1000 gram). So, 1 gram is equivalent to 0.001 litre. 1 litre of chemically pure water has a mass of 1 kg at 277.13 K (3.98 °C or 39.164 °F), at which point the pure water occupies the minimum volume per mass.

Answer 3

There is no direct answer to this - grams are a measure of weight, a liter is a measure of volume, in the metric system. That's like asking how many pounds are in a gallon. A gallon of water weighs less than a gallon of gasoline.

Actually there is if you assume a density. Density links mass and volume and has the units of grams per millilitre. Water close to room temperature has a density of 1g/ml, and assuming this, 1 litre would be a kilogram

Answer 4

That would depend on what it was a liter of!

If and only if it was a liter of water it would be 1000, because a liter of water contains 1000ml and one ml of water weighs one gram. (only if it is absolutely pure water)
