µmol/L µg/dL mg/dL mg/L µg/L

Worked example

16.5 µmol/L (middle of the reference range) = 105 µg/dL

Conversion formulas

µg/dL	µg/dL = µmol/L × 6.353	µmol/L = µg/dL × 0.1574
mg/dL	mg/dL = µmol/L × 0.006355	µmol/L = mg/dL × 157.4
mg/L	mg/L = µmol/L × 0.06355	µmol/L = mg/L × 15.74
µg/L	µg/L = µmol/L × 63.55	µmol/L = µg/L × 0.01574

Reference range

Frequently asked questions

How do I convert Copper from µmol/L to mg/dL?

mg/dL = µmol/L × 0.006355. In the other direction: µmol/L = mg/dL × 157.4.

What is the reference range of Copper?

For adults the range is 11 – 22 µmol/L (Alfred Health Pathology Handbook). Reference ranges differ between laboratories and partly by sex and age; use the range printed on your lab report.

Which units are used for Copper?

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