Cortisol: µg/dL to nmol/L
1 µg/dL = 27.5893 nmol/L
Reference only. These conversions are arithmetic, not medical advice. Reference ranges differ between laboratories, and results should be interpreted by a clinician alongside the lab's own reported units and ranges.
Conversion table
| µg/dL | nmol/L |
|---|---|
| 3 µg/dL | 82.7678 nmol/L |
| 5 µg/dL | 137.9463 nmol/L |
| 10 µg/dL | 275.8925 nmol/L |
| 15 µg/dL | 413.8388 nmol/L |
| 20 µg/dL | 551.785 nmol/L |
| 25 µg/dL | 689.7313 nmol/L |
| 30 µg/dL | 827.6775 nmol/L |
| 50 µg/dL | 1,379.4626 nmol/L |
Going the other way, 1 nmol/L = 0.036246 µg/dL.
Why this conversion needs the substance
µg/dL measures mass; nmol/L measures amount of substance. Converting between them needs the molar mass of the thing being measured — for cortisol that is 362.46 g/mol. That is why a generic converter can't do it, and why every analyte has a different factor.
Jotal works this out from molar mass rather than a stored factor, so write
cortisol 20 µg/dL in nmol/L and it answers 551.785 nmol/L. Leave the substance out
and it deliberately returns nothing rather than guessing.
