Cortisol: µg/dL to nmol/L

US labs print cortisol in µg/dL, most European labs in nmol/L. To convert, multiply µg/dL by 27.589; to go back, divide nmol/L by 27.589.

Value

µg/dL

Same value in413.8nmol/L

nmol/L = µg/dL × 27.589 · molar mass 362.46 g/mol

This converter changes units only. It doesn’t tell you whether a number is in or out of any range: that depends on the range printed by your own lab, and on your doctor. Soma does not diagnose and is not medical advice.

The formula

µg/dL → nmol/L: nmol/L = µg/dL × 27.589
nmol/L → µg/dL: µg/dL = nmol/L ÷ 27.589
Where 27.589 comes from: µg/dL counts the weight of cortisol in a volume of blood, nmol/L the number of molecules. One mole of hydrocortisone, which is cortisol weighs 362.46 g; with that and the difference in volume, one nmol/L is 0.036246 µg/dL.

What the values mean

Typical ranges as the MedlinePlus Medical Encyclopedia gives them, in both units. They are for orientation only: your lab may use other ranges, and a result is read against the range printed on its own report.

Group	µg/dL	nmol/L
Blood taken at 8 a.m.	5–25	138–690

Cortisol is highest in the morning and falls through the day, so a sample taken in the afternoon or evening usually reads lower. MedlinePlus gives a range for the 8 a.m. sample only; for other times, go by your lab’s range.

About the test

Cortisol is a hormone made by the adrenal glands. It helps the body respond to stress; its level is highest in the morning and falls through the day.

About the cortisol test · Cortisol Test — MedlinePlus (U.S. National Library of Medicine).

Questions

Cortisol: what levels are typical?

MedlinePlus gives these typical ranges: Blood taken at 8 a.m.: 5–25 µg/dL (138–690 nmol/L). Labs differ in method, so your lab may use other ranges; the one on your report is the one to go by.

How do I convert cortisol from µg/dL to nmol/L?

Multiply µg/dL by 27.589. For example, 15 µg/dL is 413.8 nmol/L.

How do I convert cortisol from nmol/L to µg/dL?

Divide nmol/L by 27.589. For example, 400 nmol/L is 14.5 µg/dL.

Why is the factor 27.589?

It follows from the molar mass of hydrocortisone, which is cortisol, 362.46 g/mol, and from the volume each unit counts in.

Why does my lab’s cortisol range differ from another lab’s?

Each lab sets its range for its own method and equipment, and many ranges differ by age and sex. That’s why a result is best read against the range printed on the same report.

Soma converts straight from the PDF

Share a lab report to Soma, and it reads every row on your phone and converts the units for you, so a Quest result in mg/dL and a Synlab result in mmol/L sit on one chart, each against its own lab’s range. No account, nothing uploaded.
