Cholesterol and triglyceride converter — mg/dL ↔ mmol/L
Convert a lipid profile between mg/dL and mmol/L (used by ESC guidelines and many countries). Type a value in any field.
Lipid profile
Total cholesterolfactor 0.02586 (mg/dL → mmol/L)
LDL cholesterol
HDL cholesterol
Non-HDL cholesterol
Triglyceridesfactor 0.01129 (mg/dL → mmol/L)
Apolipoproteins
Apolipoprotein B
Lipoprotein(a)approximation only (about 2.15 nmol/L per mg/dL) — guidelines advise against converting
This converter does not include that test.
How we convert
Mass units (mg/dL) are converted to molar units (mmol/L, µmol/L) using the molar mass of the compound: mmol/L = mg/dL × 10 ÷ molar mass. Results are rounded to about 4 significant digits.
Always use the reference range printed on your laboratory report — it depends on the assay.
