What is the Fibrinogen g/L → mg/dL?

Fibrinogen in g/L — the unit of UK and Scandinavian laboratories and of most European bleeding-management guidance — is converted here into mg/dL, used in the USA, Turkey and by many laboratories in German-speaking countries. The factor is exactly 100, since 1 g/L is 100 mg/dL.

When to use it

Bringing a g/L value from a guideline or paper into the mg/dL unit of a local report
Reading US literature after a result in g/L
Comparing serial values after a change of laboratory

When not to use it

Clot-firmness values from viscoelastic tests
Fibrinogen concentrate or cryoprecipitate doses

How it is calculated

Fibrinogen (mg/dL) = fibrinogen (g/L) × 100

Clinical pearls and limitations

Converts units only; reference ranges depend on the laboratory, the assay and the patient.
mg/dL = g/L × 100; whole mg/dL are sufficient.
Record the method (Clauss, PT-derived, antigen) together with the value; a change of method between samples can mimic a real change.
Fibrinogen rises in pregnancy and inflammation; interpretation thresholds depend on context, guideline and laboratory.
Very low values may be reported as below the measuring range of the assay rather than as a number.

Frequently asked questions

How do I convert fibrinogen from g/L to mg/dL?

Multiply by 100. Example: 3.4 g/L = 340 mg/dL; 1.2 g/L = 120 mg/dL.

Why is the factor 100?

One gram is 1000 mg and one litre is 10 dL, so a concentration per litre spread over decilitres becomes 1000 mg ÷ 10 dL — 100 mg/dL for every 1 g/L.

Do mg/dL and g/L results mean the same thing clinically?

Yes, as long as the method is the same — the unit change alone does not alter the result. Differences between laboratories more often reflect the method (Clauss versus derived) and the reagent than the unit.
