µmol/L µg/dL mg/L µg/L

Worked example

14 µmol/L (middle of the reference range) = 91.6 µg/dL

Conversion formulas

µg/dL	µg/dL = µmol/L × 6.54	µmol/L = µg/dL × 0.1529
mg/L	mg/L = µmol/L × 0.06538	µmol/L = mg/L × 15.3
µg/L	µg/L = µmol/L × 65.38	µmol/L = µg/L × 0.0153

Reference range

Unit	Adults
µmol/L	10 – 18
µg/dL	65.4 – 117.7
mg/L	0.6538 – 1.177
µg/L	653.8 – 1177

Note from the source: Plasma zinc is held within about 10-18 µmol/L (65-118 µg/dL); other papers use 70-110 or 80-120 µg/dL. Levels fall during acute inflammation and with low albumin, so a single low value needs interpretation

Frequently asked questions

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

µg/dL = µmol/L × 6.54. In the other direction: µmol/L = µg/dL × 0.1529.

What is the reference range of Zinc?

For adults the range is 10 – 18 µmol/L (Zinc-dependent NF-κB signaling (Inflammopharmacology 2017, PMC): plasma zinc reference range, citing Foster and Samman). Reference ranges differ between laboratories and partly by sex and age; use the range printed on your lab report.

Which units are used for Zinc?

Common units are µmol/L, µg/dL, mg/L, µg/L.
