Conversion formulas

µg/24 h	µg/24 h = nmol/24 h × 0.1832	nmol/24 h = µg/24 h × 5.458

Good to know

Epinephrine (adrenaline) in 24-hour urine is reported in µg/24 h or in nmol/24 h.

µg/24 h × 5.46 = nmol/24 h (exact factor 5.458).
Collect the urine for exactly 24 hours into an acidified container; stress, caffeine and some drugs raise the result.
