Conversion Formulas
PPM to PPB
Formula: PPB = PPM × 1000
Example: 5 ppm = 5 × 1000 = 5000 ppb
Calculation: 1 part per million = 1000 parts per billion
PPB to PPM
Formula: PPM = PPB ÷ 1000
Example: 2500 ppb = 2500 ÷ 1000 = 2.5 ppm
Calculation: 1000 parts per billion = 1 part per million
PPM to Percent
Formula: % = PPM ÷ 10000
Example: 50000 ppm = 50000 ÷ 10000 = 5%
Calculation: 10000 ppm = 1 percent
PPM to PPT
Formula: PPT = PPM × 1000000
Example: 0.001 ppm = 0.001 × 1000000 = 1000 ppt
Calculation: 1 ppm = 1 million ppt
