Cholesterol converter

Convert any cholesterol number or triglycerides between mg/dL and mmol/L, with the charts below.

Cholesterol in mmol/LExample

5.17mmol/L

In mg/dL: 200 mg/dL
In mmol/L: 5.17 mmol/L

See the working

mmol/L = mg/dL ÷ 38.67200 ÷ 38.67 = 5.17 mmol/L

The same factor works for total, LDL, HDL and non-HDL cholesterol.

Read my lipid panel with my ApoB and Lp(a).

One factor for cholesterol, another for triglycerides

Cholesterol (total, LDL, HDL and non-HDL) converts with 38.67: divide mg/dL by 38.67 for mmol/L. Triglycerides are heavier molecules, so they use 88.57.

Mixing the two factors up is the most common conversion mistake, which is why this converter asks which number you have.
