1

There is a formula, which connects three characteristics: volume, mass and density: m = PV

Symbols for these parameters have the following form:

V – volume in ml

m is the mass, g

R – density, g/ml

The simplest example is to consider the calculations of water, which has a constant density equal to 1 g/ml.

Example No. 1. Calculate the mass of water if its volume is 500 ml.

Write down the formula m = PV

The substitute data value condition:

m (water) = 1 g/ml x 500 ml = 500 g

Write down the formula m = PV

The substitute data value condition:

m (water) = 1 g/ml x 500 ml = 500 g

3

Similarly, it is possible to translate ml to grams, not only for water but also other substances. It's important to know the density values, which are reference material. They can be found in textbooks of physics, chemistry, or the web. In addition, sometimes the volume can be given in milliliters and in liters, cubic centimeters or meters. In this case, the suggested data must necessarily convert to milliliters, and then carry out further calculations.

Example No. 2. Calculate the mass of vegetable oil if its volume is 200 ml.

The density of vegetable oils of different types varies in the range of 0,87-0,98 g/cm3 or 0,87-0,98 g/ml. If you know the specific density of oil, it is easy to calculate the mass.

For example, a density of 0,93 g/ml.

Substitute this value into the formula m = PV

m (oil) = 0,93 g/ml x 200 ml = 186 g

The density of vegetable oils of different types varies in the range of 0,87-0,98 g/cm3 or 0,87-0,98 g/ml. If you know the specific density of oil, it is easy to calculate the mass.

For example, a density of 0,93 g/ml.

Substitute this value into the formula m = PV

m (oil) = 0,93 g/ml x 200 ml = 186 g

If necessary, the same equation, you can perform a reverse allocation, that is, we convert grams to milliliters.

Example No. 3. Calculate the volume of water if its mass is 500 g.

Write down the formula m = PV

Print from it the volume V = m / V

Substitute offered in the condition value:

V (water) = 500 g / 1 g/ml = 500 ml

Example No. 3. Calculate the volume of water if its mass is 500 g.

Write down the formula m = PV

Print from it the volume V = m / V

Substitute offered in the condition value:

V (water) = 500 g / 1 g/ml = 500 ml

Useful advice

The calculations should take into account that the density of the same substances may vary depending on their concentration. These data are also listed in the directories.

# Advice 2 : How to convert grams to milliliters

In most recipes, many ingredients are indicated in grams. How to take the right amount of product when you do not have accurate kitchen scales? Actually can be quite simple to calculate how many milliliters will be in the number of grams. And measure out the desired amount in a measuring Cup it will be much easier. Made a one-time measurement for a specific product you can save. So pretty quickly you will receive your own table, frequently used dimensional values.

You will need

- A pen and a piece of paper

Instruction

1

Find reference information about the measured product and write down the value of its density.

2

3

The mass of a substance is split into a reference density value. The result of the action will correspond to the volume of product in cubic meters.

4

Translate cubic meters to

**milliliters**. To do this, the result of previous actions multiply by 1000000. The result is our desired value is the volume in milliliters for this product. You can then measure in a measuring Cup specified quantity.Note

The density of the product should be given in the reference in the SI metric system, i.e. it is specified in units of kg/m3.

Useful advice

Sometimes in a table reference point is not the exact number, but the range of density values, such as buckwheat 1180-1280 kg/m3. In this case, you should take the average value of these values, as it is closest to the density given in less precise tables.

# Advice 3 : How to convert ml to liter

The abbreviation "ml (Milli

**liter**) oboznalsya volumetric characteristics of the relatively small amount of a substance. Milli**liter**is derived from the**liter**, thousandth. Liter and all its derivatives are not part of the SI. In this system, one Milli**liter**from corresponds to a volume equal to one cubic centimeter, and**liter**- equal to one cubic decimeter.Instruction

1

Divide by a thousand known value of the amount of the substance in Milli

**liter**Ah to convert it into**liter**s.2

Take, for example, the calculator from Windows, if you calculate the value in the mind difficult. To run it can be opened by pressing WIN or click on the "start" button the main menu and selecting the subsection "Standard" under "All programs", point to "Calculator". Because it is a system component, then typing a short command calc and press Enter to open the calculator and through dialogue run programs. This dialog can be accessed by pressing the key combination WIN + R or by selecting the string "Run" menu on the "start"button.

3

Switch the calculator interface mode conversion of measurement units. To do this, expand the "View" menu and click "Transfer of values". This version of the design of the calculator is to the left of the three fields to select units of measurement and the "Translate" button under them.

4

Click the top of the list ("Category") and select the line "Volume". When setting the value in this field, the calculator changes the composition of units in the other two lists. The average of these ("Initial value") select "Milli

**- litre**". At the bottom ("Final value") click the line "**liter**".5

Click the input field of the calculator and enter the known amount in Milli

**liter of**Oh. Then click the button labeled "Translate". The procedure is finished, the calculator will calculate the entered value in**a liter of**Oh.6

Another method of conversion is to use Google search engine. C of recent time there is a calculator that is also able to translate values from one unit to another. This Converter does not have a separate interface to enter a value directly in the field must enter a search query. You just need to articulate the query. For example, to find the value corresponding to the fifteen hundred Milli

**liter**s, type in "1500 ml per**liter of**Oh".# Advice 4 : How to convert grams to milliliters

In grams measured body mass in any physical state, in milliliters is the volume of the liquid. The mass of a substance depends on its density, which in turn depends on physico-chemical properties of substances and external conditions. We will understand how to align those physical quantities.

3

The value of the density of the material in the Handbook may be given in different units. If the density is specified in kg/cubic m - set the value of the density in g/CC and ml To do this, move the kilograms to gramsand cubic meter - milliliters. Then substitute in the numerator and denominator of the respective units, and they multiply the table value density: the density (from table) * 1000 g/1 000 000 ml.

4

Use the calculator to calculate the amount of material: divide the mass by the density.

Don't forget about the units!

The resulting value will determine the ratio of the mass of a substance in grams by its volume in milliliters.

To eliminate the error in the calculations, carefully handle the units.

Useful advice

1 kilogram – 1000 grams. 1 liter – 1000 milliliters.

It is considered that 1 gram of water equals 1 milliliter 1 liter of distilled water at a temperature of + 4oC weighs about 1 kg (density of water under these conditions is 1000 kg/cubic meter). The change in the density of tap water (the ratio of body mass to the volume that it occupies), due to changes in pressure and temperature of the ambient air in the home is usually not taken into account. When more accurate calculations (for example, when determining the mass of ballast on ships) - it takes into account everything.

If we talk about water density - the sea water is heavier than fresh. This is due to the presence of salts. Other substances density is also more or less changes depending on external factors: pressure, humidity and ambient temperature. In this case, the substance is more hygroscopic (absorbs moisture intense), the larger changes in density. That is the same capacity of a certain volume, filled with substances with different density will have different mass. For example, the density of the sand, depending on the maintenance in it of water changes by about half.

For the convenience of users, there are conversion chart grams to milliliters for many food products. On the basis of these tables are made of plastic measuring mug for kitchen liquid and solids.
