ConverterReverse conversion: ppm to ppb
ppb to ppm Converter - Parties par milliard to Parties par million
Parties par milliard (ppb) to Parties par million (ppm)
Direct answer
1 ppb = 0.001 ppm
ppm = ppb × 0.001
Converter
Conversion formula
ppm = ppb × 0.001
ppb = ppm × 1,000
Example: 10 ppb = 10 × 0.001 = 0.01 ppm.
Note: Generic aqueous approximation; ppb can mean different concentration bases in other contexts. Generic aqueous approximation; ppm can mean different concentration bases in other contexts.
