Fibrinogen Unit Converter
Fibrinogen (Factor I) is a soluble plasma glycoprotein essential for blood coagulation. It is converted by thrombin into fibrin strands during clot formation.
Fibrinogen levels are critical in diagnosing bleeding disorders and disseminated intravascular coagulation (DIC). Results are typically reported in mg/dL in the US, while international laboratories use g/L. This tool provides instant conversion between these units.
Standard Unit
USMilligrams per deciliter.
SI Unit
Grams per liter.
Clinical Context
Reference Range (Adults):
• 200 – 400 mg/dL (2.0 – 4.0 g/L).
Hypofibrinogenemia (< 150-200 mg/dL):
Seen in DIC, advanced liver disease, massive transfusion, and congenital afibrinogenemia. Levels < 100 mg/dL often trigger Cryoprecipitate transfusion in bleeding patients.
Hyperfibrinogenemia (High Levels):
Fibrinogen is an Acute Phase Reactant. Levels rise in inflammation, infection, trauma, malignancy, and pregnancy.
Conversion Logic:
1 g/L = 100 mg/dL.
1 mg/dL = 0.01 g/L.

Frequently Asked Questions
Yes. 1 gram per liter is numerically identical to 1 milligram per milliliter. However, clinical labs typically report in g/L for SI.
Fibrinogen is a large, complex protein with variable molecular weights depending on the variant. Mass units (g/L) are universally preferred over molar units for this protein.
