Bilirubin: mg/dL to µmol/L

Convert Bilirubin between mg/dL and µmol/L — Total bilirubin is reported in mg/dL in the US and µmol/L elsewhere. Type in either box to convert both ways.

Reference range. Typical total bilirubin is about 0.1–1.2 mg/dL (2–21 µmol/L); higher levels can cause jaundice.

How to convert Bilirubin from mg/dL to µmol/L

To convert Bilirubin, multiply mg/dL by 17.1 — bilirubin has a molar mass of 584.66 g/mol. For example, 1 mg/dL equals 17.104 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 Bilirubin from mg/dL to µmol/L?

Multiply mg/dL by 17.1 — bilirubin has a molar mass of 584.66 g/mol. For example, 1 mg/dL is 17.104 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 Bilirubin level?

Typical total bilirubin is about 0.1–1.2 mg/dL (2–21 µmol/L); higher levels can cause jaundice. 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 0.3 to 20 mg/dL, or 5.1312 to 342.08 µmol/L, so a range quoted in either system can be lined up against your own figure.

Why is Bilirubin reported in different units?

Total bilirubin is reported in mg/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 Bilirubin result. The two boxes above are labelled mg/dL and µmol/L, so you can read a value in whichever system your own report uses.

Is this Bilirubin converter accurate and free?

Yes — this Bilirubin 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.
