1 ng/mL = 0.1308 nmol/L. Nothing you type here leaves your browser.
The conversion
- 1 ng/mL = 0.1308 nmol/LFrom ng/mL to nmol/L: divide by 7.647. Back again: multiply by 7.647.
Mass and molar units are linked by the molecular weight: 7,647 g/mol (Mature IGF-1, a 70-amino-acid protein. Labcorp states a molecular weight of 7647; Mayo gives about 7.6 kDa. Common labs convert with ng/mL x 0.131 = nmol/L.). Source: Labcorp.
Common values
From zero to about twice the usual upper limit, plus the usual limits themselves.
