Pantothenic Acid (Vitamin B5) Unit Converter
Pantothenic Acid (Vitamin B5) is a water-soluble vitamin essential for the synthesis of Coenzyme A (CoA). While deficiency is rare (known historically as “burning feet syndrome”), levels are sometimes measured in nutritional assessments.
This converter facilitates switching between mass units (ng/mL, μg/L) commonly used in clinical reports and SI molar units (nmol/L, μmol/L) used in research and international contexts.
Mass Units
StandardNanograms per milliliter (Numerically equivalent to μg/L).
SI / Molar Units
Clinical Context
Reference Values: Reference ranges vary by laboratory.
• Whole Blood: Typically 200 – 1800 ng/mL.
• Urinary Excretion: Often considered the most reliable indicator of status (<1 mg/day suggests deficiency).
Conversion Logic:
Molecular Weight of Pantothenic Acid: ~219.235 g/mol.
1 ng/mL ≈ 4.56 nmol/L.
1 nmol/L ≈ 0.219 ng/mL.

Frequently Asked Questions
No. Pantothenic acid is found in almost all plant and animal foods (hence the name from Greek “pantos” meaning “everywhere”). Severe deficiency is extremely rare.
Whole blood, serum, or 24-hour urine collection can be used. Urinary excretion is often preferred for assessing recent dietary intake.
