Cortisol Converter (µg/dL ↔ nmol/L)
Convert serum cortisol between US µg/dL and SI nmol/L with the 27.59 factor.
Multiply µg/dL by 27.59 for nmol/L. Anchors: 15 µg/dL = 414 nmol/L (typical morning), normal morning ~7–25 µg/dL. Cortisol follows a steep daily rhythm — high at waking, low at midnight — so the *timing* of the draw is everything; the same number is normal at 8 a.m. and abnormal at 11 p.m. Dynamic tests (suppression/stimulation) interpret it, never a lone value.
