How to convert Iron from µg/dL to µmol/L
To convert Iron, multiply µg/dL by 0.179 — iron has an atomic mass of 55.85 g/mol. For example, 1 µg/dL equals 0.179 µmol/L. The converter above runs the exact factor at full precision and updates as you type; the swap button flips the direction.
Frequently asked questions
How do you convert Iron from µg/dL to µmol/L?
Multiply µg/dL by 0.179 — iron has an atomic mass of 55.85 g/mol. For example, 1 µg/dL is 0.179 µmol/L. The converter above does this instantly and works both ways — type a value in either box. It uses the exact factor at full precision, so the result matches published clinical conversions.
What is a normal Iron level?
Typical serum iron is about 60–170 µg/dL (10.7–30.4 µmol/L), slightly higher in men; it swings through the day and with diet. These are general adult figures only — the reference interval on your own lab report is what applies to you, and it can differ by lab, method, age and sex. The conversion table above runs from 30 to 170 µg/dL, or 5.37 to 30.4 µmol/L, so a range quoted in either system can be lined up against your own figure.
Why is Iron reported in different units?
Serum iron is reported in µg/dL in the US and µmol/L elsewhere. The two systems describe the same measurement, so a value converts exactly from one to the other with no loss of meaning — only the units and the number change. That is why guidelines, journals and lab reports from different countries quote different numbers for the same Iron result. The two boxes above are labelled µg/dL and µmol/L, so you can read a value in whichever system your own report uses.
Is this Iron converter accurate and free?
Yes — this Iron converter is both accurate and free. It applies the standard, published conversion factor at full double precision in your browser, with nothing uploaded or stored, and there is no sign-up or usage limit. It converts units only and does not interpret or diagnose results.
This is a unit-conversion reference tool, not a diagnosis or medical advice. Reference intervals are general adult guides that vary by laboratory, method and individual — always read your result against the range printed on your own report and discuss it with a qualified healthcare professional.
