Concentration Measurement Guide

Understand how ppm relates to ppb and other common concentration units used in chemistry and environmental science.

ppm to Concentration Units

1 ppm (parts per million) = 1000 ppb = 0.0001% = 1 mg/L (water)
1 ppb (parts per billion) = 0.001 ppm = 0.0000001% = 1 μg/L (water)
1 ppt (parts per trillion) = 0.001 ppb = 0.000001 ppm = 1 ng/L (water)
1% (percent by volume) = 10,000 ppm = 10,000,000 ppb
1 mg/L (milligram per liter) = 1 ppm (for dilute aqueous solutions)

These conversions follow standard measurement conventions for chemical concentrations in solutions and gases.

Common Concentration Measurements

Water Quality

Safe drinking water: Chlorine ≈ 0.2-4 ppm, Fluoride ≈ 0.7-1.2 ppm, Nitrates < 10 ppm

Industrial Chemicals

Cleaning solutions: 500-5000 ppm, Cooling water treatment: 10-500 ppm

Environmental

Air quality: Ozone limit ≈ 0.075 ppm, Water contaminants: Heavy metals < 10 ppb

Medical & Food

Saline solution: 9000 ppm NaCl, Blood glucose: ~100 mg/dL (≈5.5 mmol/L)

For aqueous solutions, 1 ppm is approximately 1 mg/L and 1 ppb is approximately 1 μg/L due to water's density.

ppm to ppb Use Cases
