Ozone Conversions & Equations
Physical Properties, Standard conditions P = 101325 Pa, 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/m3
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 = 7,284 PPM Ozone
Ozone Concentration in Oxygen by Weight
- 100 g O3/m3 = 6.99% O3 (Approximate)
- 1% O3 = 14.3 g O3/m3 (Approximate)
- 1% O3 = 6,520 PPM Ozone
Ozone Calculator
(3.78 X 60 X LPM/4.54 X PPM) / 1000 = g/hr
Output of an Ozone Generator from g/m3 of Ozone
SLPM X 60 X 0.001 X g/m3 = g/hr
Output of an Ozone Generator from PPM of Ozone & Flow Rate
CFM / 35.33569 X 60 X PPM X 2.14 = mg/hr
Flow Rate and Desired PPM Conversion in Water
Use this calculation to determine the necessary ozone production to achieve a specific ozone dosage into a water flow.
