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 = 7284 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 = 6520 PPM Ozone
Adjust Flow Rate Conversion
Ozone Dosage into Water
- GPM • 3.78 •60 • PPM = mg/hr
