1 mg/dL = 0.0259 mmol/L. Nothing you type here leaves your browser.

The conversion

1 mg/dL = 0.02586 mmol/LFrom mg/dL to mmol/L: divide by 38.67. Back again: multiply by 38.67.
1 mg/dL = 0.01 g/LFrom mg/dL to g/L: divide by 100. Back again: multiply by 100.

Mass and molar units are linked by the molecular weight: 386.65 g/mol (Cholesterol, C27H46O (PubChem lists 386.7). Non-HDL-C is the mass of cholesterol carried in all non-HDL particles, so the cholesterol molecular weight applies.). Source: PubChem (National Library of Medicine).

Common values

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