Convert mg/dL to nmol/L (and back)
How to convert a value from your report into other units — with the formula and examples.
mg/dL=nmol/L
nmol/L = mg/dL ÷ M × 10⁷, for a substance with molar mass M, g/mol
How it works
Milligrams per deciliter are typical of US reports, nanomoles per liter of European ones. Once again the factor depends on the substance: the number in nmol/L = the number in mg/dL multiplied by 10⁷ and divided by the molar mass.
Examples for common markers
| Marker | Molar mass / valence | Conversion example |
|---|---|---|
| Cortisol | 362,5 | 18 mcg/dL = 500 nmol/L |
| Creatinine | 113,1 | 1.0 mg/dL = 88.4 µmol/L (not nmol!) |
| Glucose | 180,2 | 100 mg/dL = 5.6 mmol/L |
| Urea | 60,06 | 28 mg/dL = 4.7 mmol/L |
Watch the order of magnitude: glucose and urea are more often needed in mmol/L (factors ×0.0555 and ×0.1665 respectively from mg/dL), not nmol/L.
