Vitamin C Unit Converter
Vitamin C (Ascorbic Acid) is a powerful water-soluble antioxidant essential for collagen synthesis, immune function, and wound healing. Unlike most animals, humans cannot synthesize Vitamin C and must obtain it from their diet.
Serum levels are used to diagnose deficiency (Scurvy) or monitor supplementation. This converter facilitates switching between standard mass units (mg/dL) and international SI molar units (μmol/L).
Mass Units
StandardMilligrams per deciliter (Common US Unit).
SI Units / Molar
Micromoles per liter (International Standard).
Clinical Context
Reference Ranges (Plasma/Serum):
• Normal: 0.4 – 2.0 mg/dL (23 – 114 μmol/L).
• Deficiency: < 0.2 mg/dL (< 11.4 μmol/L).
Clinical Significance:
• Scurvy: Severe deficiency resulting in bleeding gums, petechiae, bruising, joint pain, and impaired wound healing.
• Toxicity: Rare, but mega-doses can cause gastrointestinal distress and kidney stones.
Conversion Logic:
Molecular Weight of Ascorbic Acid: 176.12 g/mol.
1 mg/dL ≈ 56.78 μmol/L.
1 μmol/L ≈ 0.0176 mg/dL.

Frequently Asked Questions
No. 1 mg/dL = 10 mg/L. Deciliter (dL) is one-tenth of a Liter (L).
SI units (molar concentration) allow scientists to compare the number of molecules present, which is often more physiologically relevant than weight.
