Vitamin B1 (Thiamine) Unit Converter
Thiamine (Vitamin B1) is a water-soluble vitamin essential for glucose metabolism and nerve function. Deficiency can lead to serious conditions like Beriberi and Wernicke-Korsakoff syndrome.
Thiamine levels are typically measured in whole blood or plasma. This calculator allows for conversion between standard mass units (μg/L, ng/mL) and the international SI molar unit (nmol/L).
Mass Units
StandardMicrograms per liter (Equivalent to ng/mL).
SI Units / Molar
Nanomoles per liter (International Standard).
Clinical Context
Reference Ranges (Whole Blood):
• Normal: 2.5 – 7.5 μg/dL (74 – 222 nmol/L).
Note: Reference ranges vary significantly by laboratory and sample type (plasma vs. whole blood).
Clinical Significance:
• Deficiency: Alcoholism, chronic malnutrition, malabsorption, dialysis. Symptoms include confusion, ataxia, and ophthalmoplegia (Wernicke’s).
Conversion Logic:
Molecular Weight of Thiamine (Hydrochloride): ~337.27 g/mol (often used for clinical calc).
1 μg/L ≈ 2.965 nmol/L.
1 nmol/L ≈ 0.337 μg/L.

Frequently Asked Questions
Yes. 1 microgram per liter is numerically identical to 1 nanogram per milliliter.
Whole blood is often preferred over plasma because most thiamine is located within red blood cells.
