Conversion Formulas & Calculations
PPM to PPT Formula
PPT = PPM × 1,000,000
Example: 5 ppm = 5 × 1,000,000 = 5,000,000 ppt
Calculation: 5 × 10⁶ = 5,000,000
PPT to PPM Formula
PPM = PPT ÷ 1,000,000
Example: 2,000,000 ppt = 2,000,000 ÷ 1,000,000 = 2 ppm
Calculation: 2,000,000 ÷ 10⁶ = 2
Scientific Notation
1 ppm = 1 × 10⁶ ppt
1 part per million equals one million parts per trillion
Ratio: 1:1,000,000
Mass Concentration
1 ppm = 1 mg/L (water)
1 ppt = 0.001 mg/L (water)
For aqueous solutions at standard conditions
