There is no simple relationship.
Weight in mg is a measure of mass (times gravity).
"ppm" (parts per million) is a measure of strength of mixture (or solution/emulsion, etc).
For this, you need to know the masses of the main body and of the "pollutant";
and then do some arithmetic.

∙ 13y agoOne can convert mg to kg by dividing milligrams by 1000.
Multiply ppm by 10000.
1 mg/kg = 1 ppm 1 mg = 1000 micrograms (ug) so 10 ug/kg = 0.01 mg/kg = 0.01 ppm
1 mg/L = 1 ppmAssumption: 1 cm3 of pure water = 1g =1000mg1 litre water = 1000 ml = 1000 g = 1 000 000 μl or 1 000 000 mg1 mg/1 litre = 1 mg/ 1 000 000 μl = 1mg/1 000 000 mg = 1 ppmNote:mg/L is most frequently used in measurements of material in water or other liquids. ppm is used as a measure of gases in other gases and is based on volume or mole ratios not weight or mass. As a clarification ppm is usually written as ppmv (parts per million volume)
Does not convert; milligrams (mg) and grams are measures of weight or mass and mL (milliliters) is a measure of volume.
To convert 1 mg of benzole trozole in 100 ml methanol to ppm, we need to consider the molecular weight of benzole trozole. If we assume the molecular weight to be 150 g/mol, then 1 mg in 100 ml is equal to 10 mg/L or 10 ppm.
To convert the concentration of Sr2+ from grams per kilogram to parts per million (ppm), you can use the following formula: 1 ppm = 1 mg/L = 1 mg/kg. Given that the concentration is 0.0079 g/kg, you can convert this to 7.9 mg/kg or 7.9 ppm.
You can not convert mg (weight) to volume (ml).
To convert parts per million (ppm) of a substance to grains per gallon (gpg), you need to know the atomic or molecular weight of the substance. Once you have this information, you can use the formula: gpg = ppm x (atomic/molecular weight/7000).
To convert ppm mole of H2O to ppm wt in natural gas, you need to know the molecular weight of water (H2O), which is 18 g/mol. Once you have this information, you can use it to convert between the two units. This conversion involves considering the molecular weight of the components in the mixture.
One can convert mg to kg by dividing milligrams by 1000.
Write an equation representing the ppm concentration: ppm = mass solute (mg) ÷ volume solution (L) Extract the data from the question: mass solute (NaCl) = 0.0045 g. ... Convert the mass in grams to a mass in milligrams: mass NaCl = 0.0045 g = 0.0045 g × 1000 mg/g = 4.5 mg.
PPMV stands for parts per million by volume, a unit of measurement used to express the concentration of a substance in a gas. It indicates the number of parts of a particular substance per million parts of the total gas volume.
5 parts per million (ppm) is the same as 5 milligrams per kilogram (mg/kg) for a solution.
To convert 5000 ppm to milligrams per liter (mg/L), you need to know the density of the substance in question. Once you have the density, you can convert mg/L to milliliters (ml) using the density of the substance.
Assuming you really mean 1 g/ml (which is very high), then ... convert 1 gm/ml to mg/liter to get ppm1 g = 1000 mg 1 ml = 0.001 L 1000 mg/0.001 L = 1,000,000 mg/L = 1,000,000 ppm
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
