Triglycerides Unit Converter (mg/dL ↔ mmol/L)
Convert triglycerides between mg/dL and mmol/L in either direction. Enter a value and the result updates instantly. This page performs unit conversion and cites where the factor and the reference intervals come from; it does not interpret your value.
The triglycerides conversion factor and where it comes from
Triglycerides are the principal lipid form in which fat is transported in serum, reported on a standard lipid panel. Triglycerides are reported in mg/dL on U.S. lab reports and in mmol/L on UK, Canadian, Australian, and most European reports.
The standard conversion factor for triglycerides is 0.01129, applied as mg/dL × 0.01129 = mmol/L (and mmol/L ÷ 0.01129 = mg/dL in reverse). The 0.01129 factor is smaller than for cholesterol because the assumed average triglyceride molecule (triolein, 885.4 g/mol) is heavier than cholesterol.

Published reference intervals
The intervals below are reproduced from U.S. National Library of Medicine, MedlinePlus: Triglyceride level. They are listed here for unit reference only. Whether any value is in range for you depends on your laboratory's own reference range and your clinical context, so read them alongside your report and your healthcare provider, not in place of either.
| Category | mg/dL | mmol/L |
|---|---|---|
| Normal | Less than 150 mg/dL | Less than 1.70 mmol/L |
| Borderline high | 150-199 mg/dL | 1.70-2.25 mmol/L |
| High | 200-499 mg/dL | 2.26-5.64 mmol/L |
| Very high | 500 mg/dL and above | 5.65 mmol/L and above |

Common questions
How do I convert triglycerides from mg/dL to mmol/L?
Multiply by 0.01129: mg/dL × 0.01129 = mmol/L. To go the other way, divide by 0.01129 (or multiply by 88.57).
What is the triglycerides conversion factor?
0.01129. The 0.01129 factor is smaller than for cholesterol because the assumed average triglyceride molecule (triolein, 885.4 g/mol) is heavier than cholesterol.
Where is mg/dL used and where is mmol/L used?
Triglycerides are reported in mg/dL on U.S. lab reports and in mmol/L on UK, Canadian, Australian, and most European reports.
