Copper (Cu) Unit Converter
Copper (Cu) is an essential trace element required as a cofactor for several critical enzymes, including cytochrome c oxidase (for energy production), superoxide dismutase (antioxidant defense), and ceruloplasmin (iron metabolism). Once absorbed, copper is primarily transported bound to Ceruloplasmin (approx 95%) and albumin.[Image of copper metabolism pathway and transport]
Clinically, copper levels are measured to diagnose disorders of copper metabolism. Low copper levels are seen in **Menkes disease** and some forms of severe malnutrition. Conversely, high copper levels, particularly high free (unbound) copper, are the hallmark of Wilson’s Disease, a genetic disorder causing copper accumulation in the liver, brain, and eyes (Kayser-Fleischer rings). Accurate unit conversion is essential for applying global treatment guidelines.

Clinical Context
Reference Range: Serum copper levels in healthy adults typically range from 70 – 140 µg/dL (11 – 22 µmol/L).
Total serum copper may be low in Wilson’s disease due to low ceruloplasmin synthesis, but free (unbound) copper is dangerously high. High levels are often associated with infection, inflammation, or estrogen use. The conversion factor relies on the atomic mass 63.546 g/mol: 1 µmol/L $\approx$ 6.35 µg/dL.

Frequently Asked Questions & Tips
No. $1 \text{ mg/L} = 100 \mu\text{g/L}$, while $1 \mu\text{g/dL} = 10 \mu\text{g/L}$. They differ by a factor of 100.
No. In Wilson’s disease, total copper is low, but free copper is high, meaning a high risk of toxicity.
