40 mg/dL to mmol/L (Total Cholesterol)
The answer, the conversion math, and a table of nearby cholesterol values. Unit conversion only; this page does not interpret the value clinically.
How 40 mg/dL of total cholesterol converts to mmol/L
Total cholesterol is the sum of the cholesterol carried by all lipoproteins in serum, reported on a standard lipid panel. Total cholesterol is reported in mg/dL on U.S. lab reports and in mmol/L on UK, Canadian, Australian, and most European reports.
The conversion factor used here is 0.02586. The 0.02586 factor is shared by total cholesterol, LDL, HDL, and VLDL because all four are reported as the mass of the same cholesterol molecule (molecular weight 386.65 g/mol). Applied here: 40 mg/dL × 0.02586 = 1.034 mmol/L.
