First, we will analyze a little.
One milliliter is a unit of the volume of liquids or bulk substances and it is equal in volume to one cubic centimeter
;
Translated mg to ml. Translated ml to mg.
Necessity translate ml (milliliters) to mg (milligrams) and vice versa usually occurs when calculating dosages of drugs.
Consider several cases.
1) If you need to calculate the amount of mg in a ml of a certain solution, then you need to remember that:
100 ml of a solution with a concentration of 1% contains 1 grams of the active (active) substance.
Since 1 gram = 1000 milligrams, in 1 ml of a solution, a concentration of 1% will be 1000 /100 – 10 mg.
Translating ml into mg in this case is very simple – just add a nolik to the percentage of the solution of the solution.
For example:
1 ml of 10% solution will be contained 100 mg.
10 ml of 10% solution will be contained 1000 mg.
1 ml of a 15% solution contains 150 mg.
and t.D.
2) another option – there is a dosage of the drug in mg (milligrams), and we need to transfer this dose into ml of syrup or suspension.
In this case, the information contained in the annotation of the drug will help us. It indicates how much mg will be contained in the total volume. For example:
Sumamed 100 mg / 5 ml suspension – 5 milliliters contain 100 mg of active substance. So, in 1 milliliter there will be 100 /5 = 20 milligrams.
Paracetamol suspension 120 mg / 5 ml – here in 5 ml will be 120 mg, in 1 ml: 120 /5 = 24 mg.
Thus, if we know the dose in milligrams, then it will be easy to transfer it to milliliters – it is enough to know the share of active substance.
Example.
The dose of the drug is 15 mg per 1 kg of body w8. For example, if the weight is 20 kg, then the dosage = 15 * 20 = 300 mg.
If in the annotation to the suspension it is written that 5 ml contains 120 mg, then you can transfer MG into ml in this way:
120 mg – 5 ml.
300 mg – x ml.
120x = 300 * 5 -> x = 1500 /120 = 12.5 ml.
Or:
1ml contains 120 /5 = 24 mg, and we need 300. So, divide 300 by 24 and get all the same 12.5 ml.
3) if you need to transfer ml to mg on the contrary, then information about the content of the active substance will also help us.
For example, we were prescribed 10 ml of a drug suspension with a concentration of 200 mg / 5ml. Accordingly, we consider the dose in the police as follows:
200 mg – 5 ml.
x mg – 10 ml.
Hence x = 400 mg.
So, 10 ml will be equivalent to 400 mg.
Very often, many confuse milliliters with milligrams, believing that this is almost the same thing, but a milliliter is a unit of volume, and milligrams are a unit of mass.
In order to calculate the amount of milliliters, it is necessary to multiply milligrams by the density of the substance and divide by 1000, we look at the density itself in a special table.
In order to calculate the number of milligrams, it is necessary to multiply milliliters by 1000 and divide by the density of this substance.
To do this, you need to understand that a ml is a measure of volume, and mg is a measure of w8.
mg – milligrams, that is, one thousandth gram.
ml – milliliter, that is, one thousandth liters.
Suppose you know how many milliliters of liquid you have, and you want to find out how much it is in milligrams.
To find out, you can without calculations, just use ultra -precise scales.
But few people have such, so you can use the calculated way.
To do this, you need to know the weight of the liter of your liquid.
This can be found by a special table of liquid densities.
There is a density in g/cm³, that is, they show how much 1 milliliter of a certain liquid weighs (cm³ is a milliliter).
Now knowing how many milliliters you have, you can calculate how many milligrams you have.
Suppose you have 15 ml of kerosene. According to the table, its density is 0.82 g/cm³.
Multiply 15 ml by 0.82 g/cm³ and get that it will weigh 12.3 grams.
But since you need not in grams, but in milligrams, then you multiply this result by another 1000, because it is 1000 milligrams.
And it turns out that 15 ml of kerosene weigh 12300 milligrams.
It all depends on what we need to calculate.
If we are talking about clean water, then the rule is simple. 1 mg = 1 ml, since the density of water is equal to 1.
If we are talking about solving problems in physics (or application in everyday life), when there is a well -known liquid and its volume, and it is necessary to find the mass, then we calculate by the formula: mass (kg) = volume (m³) x density (kg/m³). It is necessary to take just such measures, since they go in the SI system, and after recalculating milliliters and milligrams. For example, linseed oil density is 940 kg/m³. 1000 milliliters are 1 liter, and 1 liter in the SI system is 0.001 m³. It comes from here that the mass of five liters of the desired oil is: M = 0.005 x 940 = 4.7 (kg). Now we transfer to milliliters – 4.7 x 1000 = 4700 (mg).
It is worth immediately paying attention to the fact that milligrams are a unit of measurement of mass, and a milliliter is a unit of measurement of volume. To translate one of milligrams into milliliters, you need to know the density of this substance. Typically, such a translation of units is carried out for liquid substances.
For example, we have the number of milligrams of a certain substance and we need to translate them into milliliters. To do this, you need to multiply the amount of substance in milligrams by the density of the substance (g/cm.cube) and divide 1000.
For the clarity of the use of this formula, consider an example of a translation of 10 mg. Millilitra honey. Honey density 1.35 g/cm cube.
Now we translate: 1.35*10/1000 and get 0.0135 ml.
This is considered according to the formula in which the mass = volume multiplied by density. The latter can be found in special reference tables. Water density = 1, respectively, the mass will be = volume. Typically, the density is indicated in g/l, this must be taken into account when counting by mg and ml (divide by 1000).
It is easier to do it with water- 1 milliliter of water = 1 gram, in which is a thousand milligrams, but by the way, a milligram of weight, and milliliter is volume, and
( nothing personal.)
If you are dealing with water (and this is most often), then 1 ml is 1 mg. In general, if you do not need special accuracy of any liquid (not thick), you can count. But if you need to know for sure, then you need to know the density of the substance and then calculate by the formula:
ml = mg*density/1000
Milliliters (ml) and milligrams (mg) are measures, respectively, volume and mass. When calculating the translation of the amount of any substance from one measure to another, is used for the initial example, as a non-mathematically accurate standard, water.
From the calculation that 1 ml of water (approximately) is 1 g (that is, 1000 mg) of water, a translation from one to another is carried out as follows:
5 ml are 5000 mg. Otherwise say – 5 g.
10,000 mg are 10 ml. Otherwise say – 10 g.
When calculating with any other substances in the formula, the density of these substances is included.
Milliliters are volume, and more precisely, this is a non -systemic metric unit of volume.
Milligrams are a pre -unit of measurement of mass, in the international system of SI.
Milliliter is a unit of volume measurement: 1 ml is 0.001 l.
Milligrams are a unit of mass measurement: 1 mg equal to 0.001 gr.
Conclusion 1 ml is 1 mg.
