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