µg/24 h nmol/24 h

Worked example

20 µg/24 h (middle of the reference range) = 315 nmol/24 h

Conversion formulas

nmol/24 h	nmol/24 h = µg/24 h × 15.74	µg/24 h = nmol/24 h × 0.06355

Good to know

Copper in 24-hour urine is reported in µg/24 h or in nmol/24 h.

µg/24 h × 15.7 = nmol/24 h (1 nmol/24 h = 0.0636 µg/24 h).
Use metal-free collection containers. 24-hour urine results depend on a complete collection; a missed portion lowers the value.

Reference range

Unit	Adults
µg/24 h	10 – 30
nmol/24 h	157.4 – 472.1
