The conversion

1 mg/g = 0.1131 mg/mmolFrom mg/g to mg/mmol: divide by 8.84. Back again: multiply by 8.84.
1 mg/g = 0.001 g/gFrom mg/g to g/g: divide by 1,000. Back again: multiply by 1,000.

g/g and mg/mg give the same number.

Mass and molar units are linked by the molecular weight: 113.12 g/mol (creatinine, the denominator of the ratio (C4H7N3O)). Source: PubChem (National Library of Medicine).
