Zinc µmol/L → µg/dL
Convert zinc from µmol/L to µg/dL
Converts units only; reference ranges depend on the laboratory, the assay and the patient.
What is the Zinc µmol/L → µg/dL?
Zinc results in µmol/L, the SI unit used in the UK and in most international nutrition literature, are converted here into µg/dL, used in the USA, Turkey and by some European laboratories. The converter divides by 0.1529 (equivalent to multiplying by about 6.54), derived from the atomic mass of zinc (65.4 g/mol).
When to use it
- Bringing a µmol/L result into the µg/dL unit of the local laboratory
- Using US references or textbook tables that list zinc in µg/dL
- Comparing parenteral-nutrition monitoring data from sites with different units
When not to use it
- Zinc protoporphyrin or other zinc-related markers
- Hair or urine zinc
How it is calculated
Zinc (µg/dL) = zinc (µmol/L) ÷ 0.1529
Clinical pearls and limitations
- Converts units only; reference ranges depend on the laboratory, the assay and the patient.
- 1 µmol/L ≈ 6.54 µg/dL; 12 µmol/L ≈ 78 µg/dL.
- Round µg/dL to whole numbers.
- Before attributing a low value to deficiency, check albumin, inflammatory markers and the time of sampling.
- An unexpectedly high value should prompt a check for haemolysis or tube contamination before any clinical conclusion.
Frequently asked questions
How do I convert zinc from µmol/L to µg/dL?
Divide by 0.1529. For example, 14 µmol/L ÷ 0.1529 = 92 µg/dL and 10 µmol/L ÷ 0.1529 = 65 µg/dL.
What is 1 µmol/L of zinc in µg/dL?
About 6.54 µg/dL, because one micromole of zinc weighs 65.4 µg and a litre holds 10 dL.
Should zinc be measured fasting?
Many laboratories prefer a fasting morning sample, because zinc falls after meals and varies over the day. The reporting laboratory's sampling instructions, including its tube requirements, take precedence.
