Conversion formulas
| mg/L | mg/L = mg/dL × 10 | mg/dL = mg/L × 0.1 |
|---|---|---|
| µmol/L | µmol/L = mg/dL × 56.78 | mg/dL = µmol/L × 0.01761 |
| µg/dL | µg/dL = mg/dL × 1000 | mg/dL = µg/dL × 0.001 |
| µg/L | µg/L = mg/dL × 10 000 | mg/dL = µg/L × 0.0001 |
Good to know
Vitamin C is reported in mg/dL or mg/L. The page converts between the units only.
- mg/L × 0.1 = mg/dL (exact factor 0.1).
- The range shown is a guide from the named source; targets and reference ranges differ between laboratories, methods and indications, so compare with the range on your own report.
