How much does a Two liter bottle of water weigh?

Answer 1

Kilograms in Two LitersHere are opinions and answers from WikiAnswers Contributors:

• This is a trick question. The kilogram is a unit of mass or weight, while the liter is a unit of liquid volume. In Canada we've used the Metric System since 1977. To compare your question to one using units in the the Imperial System, it would be like asking: How many pounds are there in a gallon? See how inane that is? The answer depends on what substance you are measuring. If it is water, the answer is about two kilograms. If it's two liters of molten lead, well, that weighs far more. (Read the related FAQ question on the right.)

• Actually if density= mass divided by volume, then mass= density times volume!!
• No conversion. You can't convert them. Kilograms are a unit of mass or weight. Liters are a measure of volume, normally associated with liquids.
• Scroll down to related links and look at "Explanation of Litre - Wikipedia".

A correction to this answer. The kilogram is the SI unit for MASS, not weight. Weight is measured in newtons.

Answer 2

Only if you think of pure water you can say:

2 liters of pure water weigh 2 kilograms

By definition, a kilo is the weight of one liter of pure water. The density of all other substances is determined by the ratio of their weights to an equal volume of water.

*Plus, you'd add the weight of the empty bottle.

Answer 3

The density of water 1g/mL.

2L = 2000mL

2000mL x 1g/mL = 2000g

2000g = 2kg

In the English system, 1kg = 2.2pounds(lb).

2kg x 2.2lb/1kg = 4.4lb

In SI units, weight is measured in Newtons(N).

2kg x 9.8m/s2 = 19.6N

Answer 4

1 liter is 2.204684pounds : therefore, 2 liters would be 4.409368

Answer 5

Kilogram is a unit of mass, not a unit of weight. A liter of water has a mass of almost exactly 1 kg, since this is how the kilogram was originally defined.

Answer 6

i think its 1 kg per liter
