1
Determine the weight in grams of the substance.Use of this balance.
Many foods are sold prepackaged.In this case, there is no question of the title itself.For example, in a standard pack of sugar, this food product is exactly one kilogram.

2
Locate the directory on the physics of the density of the desired substance.
For more accurate results of subsequent calculations use the available reference correction for pressure, humidity and air temperature.

3
The density of matter in the directory can be given in various units.If the density is indicated in kg / m - move the density in g / kub.ml.To do th
is, turn kilograms to grams and cubic meters - in milliliters.Then substitute in the numerator and denominator of the relevant units and multiply them table-density density (from the table) * 1000 g / ml of one million.
4
The calculator calculate the volume of the substance: divide the mass density.
Do not forget the unit!
resulting value will determine the ratio of the weight in grams of a substance to its volume in milliliters.

Note
To eliminate the error in the calculations, closely contact with the units of measurement.
Helpful Hint
1 kilogram - 1,000 grams.In 1 liter - 1000 milliliters.
accepted that 1 gram of water is 1 milliliter - 1 liter of distilled water at 4 ° C weighs about 1 kilogram (the density of water under these conditions is equal to 1000 kg / m).Changing the water tap density (the ratio of body weight to the volume which it occupies) due to pressure drop and ambient temperature, usually in the home is not taken into account.A more accurate calculation (for example, when determining the weight of ballast on ships) - accounted for everything.
If we talk about the density of water - sea water is heavier than fresh water.This is due to the presence of salts.Other substances density is also more or less varies depending on external factors such as pressure, humidity and ambient temperature.At the same time, more than substance hygroscopic (absorbs moisture intensely), the more significant changes in density.That is, the same capacity certain volume, filled with a substance with different density will have identical mass.For example, the density of the sand depending on the content of water varies by about half.
For your convenience, there are translation tables grams per milliliter for many food products.On the basis of these tables are made of plastic kitchen measuring cups for liquids and solids.
