What is the Albumin g/L → g/dL?

This converter turns serum albumin in g/L — the unit used in the UK, Scandinavia and many continental European labs — into g/dL, used in the USA, Turkey and US-derived formulas. The factor is exactly 10, because 1 dL is 0.1 L.

When to use it

Entering a European albumin into a formula defined in g/dL (e.g. the conventional corrected-calcium formula)
Reading US textbooks, question banks or studies after seeing results in g/L
Comparing serial values from labs with different units

When not to use it

Urine albumin in mg/L or albumin/creatinine ratios
Albumin dosing for infusion (grams of product), which is a different quantity

How it is calculated

Albumin (g/dL) = albumin (g/L) ÷ 10

Clinical pearls and limitations

Converts units only; reference ranges depend on the laboratory, the assay and the patient.
g/dL = g/L ÷ 10; one decimal place is sufficient.
In a g/dL formula, an albumin accidentally left in g/L distorts the result grossly — a plausibility check on the output catches this.
Albumin falls with acute illness, fluid loading and posture; a change between samples is not always a change in nutritional or hepatic status.

Frequently asked questions

How do I convert albumin from g/L to g/dL?

Divide by 10. Example: 42 g/L = 4.2 g/dL; 25 g/L = 2.5 g/dL.

Which unit does the corrected-calcium formula use?

That depends on the version: the conventional form expects calcium in mg/dL and albumin in g/dL, the SI form calcium in mmol/L and albumin in g/L. Use matching units throughout.

Why do some German labs report albumin in g/dl and others in g/l?

Both units are permitted and in use; laboratories choose one, so the unit on the specific report is what counts.
