Riboflavin (Vitamin B2) Unit Converter
Riboflavin (Vitamin B2) is a water-soluble vitamin essential for energy production, cell function, and metabolism of fats, drugs, and steroids. It serves as a precursor for coenzymes FMN and FAD.
Clinically, serum or plasma riboflavin levels may be measured to assess nutritional status, although functional assays (like erythrocyte glutathione reductase activity) are often preferred. This converter facilitates switching between standard mass units (μg/L, ng/mL) and SI molar units (nmol/L).
SI Units / Molar
RecommendedNanomoles per liter (International Standard).

Clinical Context
Reference Ranges (Plasma/Serum):
• Normal: Typically 40 – 240 μg/L (106 – 638 nmol/L).
• Deficiency: < 40 μg/L (< 106 nmol/L).
Conversion Logic:
Molecular Weight of Riboflavin: ~376.36 g/mol.
1 ng/mL = 1 μg/L.
1 μg/L ≈ 2.657 nmol/L.
1 nmol/L ≈ 0.376 μg/L.

Frequently Asked Questions
Clinical deficiency (Ariboflavinosis) is rare in developed countries but may occur in alcohol use disorder or malabsorption syndromes.
Yes. 1 nanogram per milliliter is numerically identical to 1 microgram per liter.
