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
