How do I convert Zinc protoporphyrin from µg/dL to µmol/L?

µmol/L = µg/dL × 0.01597. In the other direction: µg/dL = µmol/L × 62.6.

Which units are used for Zinc protoporphyrin?

Common units are µmol/L, µg/dL.

Drugs & toxicology

Zinc protoporphyrin (iron deficiency, lead exposure)

Also known as: Zinkprotoporphyrin

Enter a value in any unit and all other units fill in.

µmol/L µg/dL

1 µmol/L = 62.6 µg/dL

µmol/L	µmol/L = µg/dL × 0.01597	µg/dL = µmol/L × 62.6

Zinc protoporphyrin is reported in µg/dL or µmol/L. The page converts between the units only.

µmol/L × 62.6 = µg/dL (exact factor 62.6).
