Ozone conversions

Physical Properties, Standard conditions P = 1013.25 MB, T = 273.3 K 

  • » Density of ozone: 2.14 kg/m3
  • » Molecular weight of ozone: 48
  • » Density of oxygen: 1.43 kg/m3
  • » Molecular weight of oxygen: 32
  • » Density of air: 1.29 kg/m3
  • » Density of water: 1,000 kg/m



Useful Conversion Factors: (for water) 

  • » 1,000 liters = 1 m3 = 264 US gallons
  • » 1 gal = 3.785 liters = 3,785 ml
  • » 1 m3 = 35.3 ft3 = 264 US Gallons



Ozone Concentration in Water 

  • » 1 mg/l = 1 PPM O3 = 1 g O3/m3 water {By weight}



Ozone Concentration in Air By Volume 

  • » 1 g O3 / m3 = 467 PPM O3
  • » 1 PPM O3 = 2.14 mg O3/m3
  • » 100 pphm (parts per hundred million) = 1 ppm (parts per million)



Ozone Concentration in Air by Weight 

  • » 100 g O3 / m3 = 7.8% O3 (Approximate)
  • » 1% O3 = 12.8 g O3/m3 (Approximate)
  • » 1% O3 = 6678 PPM Ozone



Ozone Contentration in Oxygen by Weight 

  • » 100 g O3/m3 = 6.99% O3 (Approximate)
  • » 1% O3 = 14.3 g O3/m3 (Approximate)
  • » 1% O3 = 6678 PPM Ozone
