Triglyceride conversion: mg/dL to mmol/L
For triglycerides, 1 mg/dL = 0.0112905 mmol/L, and 1 mmol/L = 88.57 mg/dL.

Why triglycerides use a conventional factor
Plasma triglyceride is a mixture of molecules, so it has no single molar mass. Laboratories use the conventional factor of 88.57 mg/dL per mmol/L, which corresponds to 885.7 g/mol: 1 mg/dL = 1 ÷ 88.57 = 0.0112905 mmol/L.
Triolein, C₅₇H₁₀₄O₆, the usual stand-in, sums to 885.453 g/mol from the same atomic weights as the other analytes here, 3 parts in 10,000 less. The conventional factor is used so that a converted result matches the report it came from.
A factor fits one analyte only: 1 mg/dL of cholesterol is 0.0258622 mmol/L, as the cholesterol conversion table shows.
- mmol/L = mg/dL ÷ 88.57
- mg/dL = mmol/L × 88.57
Which countries report which unit
American and Indian laboratories usually report triglycerides in mg/dL; British, Canadian and Australian ones report mmol/L.
Worked example
- 150 mg/dL in mmol/L
- = 150 ÷ 88.57
- = 1.69358 mmol/L
