From

1 µg/24 h = 5.0702 nmol/24 h. Nothing you type here leaves your browser.

The conversion

1 µg/24 h = 5.07 nmol/24 hFrom µg/24 h to nmol/24 h: multiply by 5.07. Back again: divide by 5.07.
1 µg/24 h = 0.00507 µmol/24 hFrom µg/24 h to µmol/24 h: divide by 197.2. Back again: multiply by 197.2.

Mass and molar units are linked by the molecular weight: 197.23 g/mol (Metanephrine free base, C10H15NO3 (PubChem CID 21100)). Source: National Library of Medicine.

Common values

From zero to about twice the usual upper limit, plus the usual limits themselves.
