ppm↔mg/kg 1 ppm = 1 mg/kg. ppm↔mg/g 1 mg/g = 1000 ppm. ppm↔Whole number 1 Whole number = 1000000 ppm. ppm↔ug/kg 1 ppm = 1000 ug/kg. One ppm is equivalent to 1 milligram of a substance per liter of water (mg/l) or per kilogram of soil (mg/kg).

The conversion from mg/m2 to µg/cm2 is to divide the number (mg) by ten and simply change the units. For example; 25mg/m2 is the same as 2.5µg/cm2.

ppm↔ug/mL 1 ppm = 1 ug/mL. Molarity = (Parts Per Million (PPM) value × 0.001) / Atomic Weight Parts per million: PPM is expressed as milligrams per liter (mg/L). It measures the mass of the chemical substance or concentration per unit weight of water/solid or volume of one part of gas. One part per million is equal to 0.000001 units.

I am able to read the concentration of PM 2.5 in mg/m3. How to convert it to ppm? I have come across this formula : Concentration (ppm) = 24.45 x concentration (mg/m3) ÷ molecular weight How do you calculate the molecular weight of PM 2.5? Thanks for your reply Occupational exposure limits (OELs, TLVs, PELs, etc.) can be expressed in parts per million (ppm) only if the substance exists as a gas or vapour at normal room temperature and pressure. This is why exposure limits are usually expressed in mg/m 3. However, some OELs may be expressed in units such as fibres/cc (e.g., for asbestos).
