How many kilograms per liter?

Sometimes, to solve a practical problem, housewives have to look for an answer to the question: how many kilograms of a product per liter?

An unequivocal answer to this question, of course, does not exist. It all depends on the density of the product itself.

How to determine the mass of a liquid, if its volume is known

The exact mass of the fluid is calculated by the formula:

m = p * v, where:

  • m is the mass (in kg);
  • p is the density (in kg / m3);
  • v - volume (in m3).

Recall that 1 l = 0, 0001 m3.

However, counting the mass each time using the formula is, of course, inconvenient. Therefore, we give ready-made values ​​of what is the mass of 1 liter of some products.

How many kilograms of water per liter

The easiest will be with water. The fact is that in 1901 the liter just determined the weight of 1 kg of water. Although here, too, has its own nuances. First, the weight of 1 liter of water is 1 kg only at an atmospheric pressure of 760 mm Hg. st. and temperature 3,98ºС. Under other conditions, the density of water changes and, accordingly, its mass changes.Secondly, it turned out that the mass of the standard of the kilogram is slightly more than the mass of 1 liter of water. And since 1964, 1 l to 1 kg of water, strictly speaking, is no longer attached. But in everyday life, of course, we don’t need to go into such details. You can simply remember that 1 liter of water weighs about 1 kg.

How many kilograms per liter of other liquids

In one liter:

  • milk - 1,029 g;
  • kefir - from 1.027 to 1.039 kg (depending on the percentage of fat);
  • juice without pulp - about 1 kg;
  • juice with pulp - about 1,050 kg;
  • wines - 0.975-0.990 kg;
  • alcohol - 0,789 kg
  • sunflower oil - 0, 920-0.930 kg.
