Common Ozone Unit Conversions

Common ozone unit of measure calculators


Ozone Concentration in air by volume

mg/l, g/m3, ug/ml
ppm
pphm
mg/m3 O3

1 mg/l = 1 g/m3 = 1 ug/ml = 467 ppm O3

1 ppm = 2.14 mg/m3 O3

100 pphm (parts per hundred million = 1 ppm (parts per million)

This calculator is only used for ozone concentrations values by volume. See below for by weight conversions.


Ozone Concentration in air by weight

g/m3 O3
ppm O3
%

100 g/m3 = 7.8% O3

1% = 12.8 g/m3 O3

1% = 7,284 ppm O3

This calculator is used for converting ozone concentration units when ozone is measured in air. For oxygen use the calculaotor below.


Ozone Concentration in oxygen by weight

g/m3 O3
ppm O3
%

100 g/m3 = 6.99% O3

1% = 14.3 g/m3 O3

1% = 6,520 ppm O3

This calculaotr is used for converting ozone concentration units when ozone is measured in oxygen. For air, use the calcultaor above.
