Zinc (Zn) Unit Converter
Zinc (Zn) is an essential trace element required for the function of over 300 enzymes, playing vital roles in immune function, wound healing, DNA synthesis, and cell division.
Measurement of serum or plasma zinc is used to detect deficiency (common in malnutrition or malabsorption) or toxicity. This converter allows for seamless switching between mass units (μg/dL, μg/L) and SI molar units (μmol/L).
Mass Units
StandardMicrograms per deciliter (Common US Unit). 1 μg/dL = 10 μg/L.
SI Units / Molar
Micromoles per liter (International Standard).
Clinical Context
Reference Ranges (Plasma/Serum):
• Normal: 70 – 120 μg/dL (10.7 – 18.4 μmol/L).
Note: Samples must be collected in trace metal-free tubes (typically Royal Blue top) to prevent environmental contamination.
Clinical Significance:
• Deficiency: Acrodermatitis enteropathica, delayed wound healing, hypogonadism, diarrhea, alopecia.
• Sample Handling: Hemolysis causes falsely elevated results because red blood cells contain significantly more zinc than plasma.
Conversion Logic:
Atomic Weight of Zinc: 65.38 g/mol.
1 μg/dL ≈ 0.153 μmol/L.
1 μmol/L ≈ 6.54 μg/dL.

Frequently Asked Questions
Yes. 1 microgram per liter is numerically identical to 1 nanogram per milliliter.
Standard blood tubes often contain trace amounts of zinc in the stopper rubber, which can contaminate the sample and lead to falsely high results.
