Cholesterol Converter (mg/dL ↔ mmol/L)
Convert total, LDL and HDL cholesterol between conventional and SI units with the 38.67 factor.
All cholesterol fractions (total, LDL, HDL) share the 38.67 factor because they're the same molecule. Reference anchors: total 200 mg/dL = 5.2 mmol/L (desirable ceiling), LDL 100 = 2.6, HDL 40 = 1.0. Triglycerides use a *different* factor (88.57) — don't mix them up. US reports in mg/dL, UK/India/Europe in mmol/L.
