Bilirubin: mg/dL to µmol/L

US labs print bilirubin in mg/dL, most European labs in µmol/L. To convert, multiply mg/dL by 17.104; to go back, divide µmol/L by 17.104.

Value

Same value in17.1µmol/L

µmol/L = mg/dL × 17.104 · molar mass 584.66 g/mol

This converter changes units only. It doesn’t tell you whether a number is in or out of any range: that depends on the range printed by your own lab, and on your doctor. Soma does not diagnose and is not medical advice.

The formula

mg/dL → µmol/L: µmol/L = mg/dL × 17.104
µmol/L → mg/dL: mg/dL = µmol/L ÷ 17.104
Where 17.104 comes from: mg/dL counts the weight of bilirubin in a volume of blood, µmol/L the number of molecules. One mole of bilirubin weighs 584.66 g; with that and the difference in volume, one µmol/L is 0.058466 mg/dL.

What the values mean

Typical ranges as the MedlinePlus Medical Encyclopedia gives them, in both units. They are for orientation only: your lab may use other ranges, and a result is read against the range printed on its own report.

Group	mg/dL	µmol/L
Direct (conjugated) bilirubin	below 0.3	below 5.13
Total bilirubin	0.1–1.2	1.71–20.5

Total bilirubin includes the direct (conjugated) part; a report often lists total, direct and indirect bilirubin.

About the test

Bilirubin is a breakdown product of hemoglobin that the liver processes. When there is a lot of it, the skin and the whites of the eyes can turn yellow.

Questions

Bilirubin: what levels are typical?

MedlinePlus gives these typical ranges: Direct (conjugated) bilirubin: below 0.3 mg/dL (below 5.13 µmol/L); Total bilirubin: 0.1–1.2 mg/dL (1.71–20.5 µmol/L). Labs differ in method, so your lab may use other ranges; the one on your report is the one to go by.

How do I convert bilirubin from mg/dL to µmol/L?

Multiply mg/dL by 17.104. For example, 1 mg/dL is 17.1 µmol/L.

How do I convert bilirubin from µmol/L to mg/dL?

Divide µmol/L by 17.104. For example, 30 µmol/L is 1.75 mg/dL.

Why is the factor 17.104?

It follows from the molar mass of bilirubin, 584.66 g/mol, and from the volume each unit counts in.

Why does my lab’s bilirubin range differ from another lab’s?

Each lab sets its range for its own method and equipment, and many ranges differ by age and sex. That’s why a result is best read against the range printed on the same report.

Soma converts straight from the PDF

Share a lab report to Soma, and it reads every row on your phone and converts the units for you, so a Quest result in mg/dL and a Synlab result in mmol/L sit on one chart, each against its own lab’s range. No account, nothing uploaded.
