How do you convert triglycerides from mg/dL to mmol/L?

Divide by the molar mass. For triglycerides (885.4 g/mol), 1 mg/dL = 0.011294 mmol/L.

Why isn't there one factor for mg/dL to mmol/L?

Because mg measures mass and mmol measures amount of substance, the factor depends on the molar mass of what is being measured. Every analyte has its own.

Triglycerides: mg/dL to mmol/L

1 mg/dL = 0.011294 mmol/L

Reference only. These conversions are arithmetic, not medical advice. Reference ranges differ between laboratories, and results should be interpreted by a clinician alongside the lab's own reported units and ranges.

Conversion table

mg/dL	mmol/L
50 mg/dL	0.564717 mmol/L
100 mg/dL	1.1294 mmol/L
150 mg/dL	1.6941 mmol/L
200 mg/dL	2.2589 mmol/L
250 mg/dL	2.8236 mmol/L
300 mg/dL	3.3883 mmol/L
400 mg/dL	4.5177 mmol/L
500 mg/dL	5.6472 mmol/L

Going the other way, 1 mmol/L = 88.54 mg/dL.

Why this conversion needs the substance

mg/dL measures mass; mmol/L measures amount of substance. Converting between them needs the molar mass of the thing being measured — for triglycerides that is 885.4 g/mol. That is why a generic converter can't do it, and why every analyte has a different factor.

Jotal works this out from molar mass rather than a stored factor, so write triglycerides 250 mg/dL in mmol/L and it answers 2.8236 mmol/L. Leave the substance out and it deliberately returns nothing rather than guessing.
