Google has many special features to help you find exactly what you're looking for. Parts per million - ppm - is commonly used as a dimensionless measure of small levels (concentrations) of pollutants in air, water, body fluids, etc.

The Percent to PPM converter gives quick and accurate results based on the values you enter in the blank text field. Parts per million (z angličtiny, česky „dílů či částic na jeden milion“), zkráceně též ppm, je výraz pro jednu miliontinu (celku); někdy je tento výraz odvozován i z latinského pars per milion. ppm↔ng/ml 1 ppm = 1000 ng/ml ppm↔g/dL 1 g/dL = 10000 ppm ppm↔mg/dL 1 mg/dL = 10 ppm ppm↔lb/yd3 1 lb/yd3 = 593.27642110147 ppm ppm↔lb/gal (UK) 1 lb/gal (UK) = 99776.397913856 ppm ppm↔lb/ft3 1 lb/ft3 = 16018.46336974 ppm ppm↔lb/gal (US) 1 lb/gal (US) = 119826.42730074 ppm ppm↔oz/in3 1 oz/in3 = 1729994.0439319 ppm Convert ppm to percent or percent to ppm: This article describes the simple math used to convert between parts per million (PPM) and percentage, such as how we convert a measurement of 800 ppm of CO 2 in air (indicated on our colorimetric gas measurement tube shown at page top) and a percentage concentration of that same gas in air.
