How easy was it to use our calculator? Did you face any problem, tell us!

The ppm calculator measures the value of any quantity in the PPM(Part Per Millions), we can understand the PPM[mg/m3]. The PPM quantity is used to find the little amount of solute in a given amount of the Solution.


Definition of ppm:

“1 ppm is equivalent or equal to the 1 milligram per liter of a substance(mg/L) or 1 milligram per Kilogram(mg/Kg)”.

Ppm is a way of expressing very dilute concentration of the substances.Just like the percent out of hundred, ppm means the part out of millions.

How to calculate PPM?

We are explaining how to measure ppm:


1 Liter of water=1,000 cm^3=1Kg of water 

Now consider


1 Liter of water=1,000 cm^3=1,000,000 mm^3 of water
How to calculate PPM

For example, if we are finding the impurity of Arsenic in 1L of water, we would define it as 1 PPM of Arsenic is present in 1L of water. The parts per million calculator  finds the impurity of Arsenic in Per liter of water. The same way we can find the amount of lead(Pb), or  Arsenic(Ar) impurity in the given amount of water. 

In the figure below we have a 1 Liter  of water present in a cube and find the Arsenic values in the 1L of water and it is represented by a small cube, which is exactly 1PPM.

Why do we need the ppm formula?

We learn the PPM is a very small quantity and it  is the part per million. We require the part per million in a large amount of solutions. Using the term ppm we can express the concentration as a very small fraction of larger quantity. For example we are  finding the quantity of Arsenic in a Pool of water, the quantity would be as ppm or milligrams/Liter (mg/L).

It means 1 liter of water containing 1 millions milligram or 1,000,000 mm^3 

So we have:

                         1,000,000 mm^3  =mg/L=1 ppm

  • Percentage: equal to 1 per 100=10^2
  • Permille: equal to 1 per 1,000=10^3
  • ppm: equal to 1 per 1,000,000=10^6
  • ppb: equal to 1 per 1,000,000,000=10^9
  • ppt: equal to 1 per 1,000,000,000,000=10^12


The ppm calculation finds the  concentration of the solute ein in the solution.

Convert PPM to mg/m3:

We need to cover the  PPM to mg/m3 for gasses, it can be easy to convert the  PPM to mg/m3 by the parts per million calculator.

The formula for the conversion:

concentration (mg/m3) = 0.0409 x concentration (ppm) x molecular weight


Convert 100 ppm of NH3 into the mg/m3:


Now the molecular weight of NH3=17.03 g/mol

concentration (mg/m3) = 0.0409 x concentration (ppm) x molecular weight

Concentration of NH3 (mg/m3)=0.0409 x 100 ppm x 17.03 = 69.652 (mg/m3)

We are presenting a table conversion of 100 PPM of gasses into (mg/m3).


Gasses Output (mg/m3) Molecular weight 
(Ammonia)NH3 69.652 mg/m3 M = 17.03 g/mol
Carbon monoxide [CO] 114.561 mg/m3 M = 28.01 g/mol
Carbon dioxide [CO2] 180.001 mg/m3 M = 44.01 g/mol
Chlorine [Cl2] 289.981 mg/m3 M = 70.9 g/mol
Formaldehyde [CH2O] 122.806 mg/m3 M = 30.026 g/mol
Hydrogen [H2] 8.262 mg/m3 M = 2.02 g/mol
Methane [CH4] 65.604 mg/m3 M = 16.04 g/mol
Hydrogen Sulfide [H2S] 139.387 mg/m3 M = 34.08 g/mol
Nitrogen Dioxide [NO2] 188.181 mg/m3 M = 46.01 g/mol
Ozone [O3] 196.320 mg/m3 M = 48.00 g/mol


The concentration to ppm calculator converts the 100 PPM of gasses into the mg/m3.

The applications of ppm calculation:

There are various applications of the ppm formula in the field chemistry especially we are dealing with the impurities

  • In water treatment plants,we usually use the parts per million formula to figure out the mineral and the different gasses dissolved in water. These impurities can cause problems in the equipment, when we are transferring the water in huge quantities. We need to minimize the quantities of these impurities to reduce chances of corrosion.For finding the ppm values we need a special calculator like the parts per million calculator.
  • The other thing is that some impurities can be separated from water at a particular temperature. We raise the temperature of the water to that particular temperature and separate the impurities like Lead(Pb), Arsenic (Ar) from the water.
  • We include the mineral like Mg(Magnesium),P (Phosphorus) in ppm quantity in the mineral water. The mineral water does contain a particular quantity of minerals and the minerals are dissolved in ppm. The ppm concentration calculator is used to dissolve the minerals in the given solution of water. 

Parts per million conversion Chart:

We do use the ppm calculation chart as represented in the following table,we also define other units like (part per billion) ppb(10^9) and smallest units like(part per trillion)ppt(10^12).

The ppm calculator finds the ppm,ppb,and ppt values of the following table.

Practical examples of ppm:


A solution contains 5 g of Arsenic in 1500 grams of solution. Find the solution concentration in ppm?


ppm= [Grams of the Solute/Grams of the Solution]X 1,000,000

ppm=[5g/1500g]X 1,000,000

The quantity of Arsenic =3333.33 ppm


The quantity of Arsenic =3333ppm

We can find the ppm calculation by the ppm calculator.


How many grams of solute are dissolved in 100 grams of  1.2X 10^2 ppm solution?


ppm= [Grams of the Solute/Grams of the Solution]X 1,000,000

1.2X 10^2= [Grams of the Solute/100g]X 1,000,000

Grams of the Solute=[1.2X 10^2X100]/1,000,000

Grams of the Solute=0.012 g 

It means 0.012 g of solute are present in the solution, ppm converter can find the solute concentration.

Working of ppm calculator:

The ppm is one of the most tiniest of the calculation we are using in the chemical analysis, we can use the ppm concentration calculator to measure it :


  • Enter the ppm values
  • Enter the solution 
  • Enter the solute
  • Hit the calculate button to find ppm


The ppm converter is readily able to find the molar concentration of any impurity in a given quantity of solution.

  • The ppm value is displayed 


How can we explain ppm in terms of %age.

0.0001%, the 1 ppm=1/1,000,000 as  0.000001 or 0.0001%, , we can use the percent to ppm calculator to find the %age of impurity.

Is ppm calculated by mass or volume?

We can find both ppm by mass or volume.

ppm by mass:

ppm by mass is equivalent to milligrams per liter (mg/L). 

ppm by volume:

ppm by volume is a common way to measure the  concentrations of gasses.

Are  ppb and ppt smaller than ppm?

The ppb and ppt are smaller than ppm as the ppb=10^9, and ppt=10^12 but the ppm=10^6. The ppb and ppt values are evaluated by the ppm calculator


The ppm calculation is just too important when we are dealing with the little quantities of the impurities in the given solution. It helps to make the solution pure from impurities or keep the level to our desire. We need an especially designed ppm calculator to find the values in the given volume of the solution.
