Conversion Formulas
PPB to PPM Formula:
PPM = PPB ÷ 1000
Example: 5000 ppb ÷ 1000 = 5 ppm
PPM to PPB Formula:
PPB = PPM × 1000
Example: 2.5 ppm × 1000 = 2500 ppb
PPB to Percent:
% = PPB ÷ 10,000,000
Example: 1000 ppb ÷ 10,000,000 = 0.0001%
PPB to mg/L:
mg/L = PPB ÷ 1000
Example: 3000 ppb ÷ 1000 = 3 mg/L
