150 mg/dL in mmol/L
mmol/L is a molar unit, so the answer depends on which biomarker the mg/dL reading came from. Find your biomarker below.
| Biomarker | Factor | 150 mg/dL = |
|---|---|---|
| Glucose | 0.0555 | 8.326 mmol/L |
| Total cholesterol | 0.02586 | 3.879 mmol/L |
| LDL cholesterol | 0.02586 | 3.879 mmol/L |
| HDL cholesterol | 0.02586 | 3.879 mmol/L |
| VLDL cholesterol | 0.02586 | 3.879 mmol/L |
| Triglycerides | 0.01129 | 1.694 mmol/L |
| Calcium (total) | 0.2495 | 37.425 mmol/L |
| Magnesium | 0.4114 | 61.71 mmol/L |
| BUN (urea nitrogen) | 0.3571 | 53.565 mmol/L |
Why one mg/dL value has many mmol/L answers
mg/dL is a mass-per-volume unit (milligrams per deciliter). mmol/L is a moles-per-volume unit. To go from one to the other you have to know how heavy a single molecule of the substance is, because that determines how many moles fit in a given mass. Glucose molecules weigh about 180 g/mol; cholesterol weighs about 387 g/mol; a calcium ion weighs about 40 g/mol. The same 150 mg/dL reading therefore lands on different mmol/L numbers for each.
How to know which biomarker your reading is
Check the test name printed on the lab report next to the mg/dL value. The most common candidates are listed in the table above. If the test report uses an abbreviation you don't recognise, see our lab abbreviations reference.

Common questions
What is 150 mg/dL in mmol/L?
It depends on the biomarker. See the table on this page for per-biomarker answers.
Why does mg/dL to mmol/L have different answers?
mmol/L is a molar concentration, so each substance's mg/dL ↔ mmol/L factor is determined by its molecular weight. Glucose (180 g/mol) has a different factor than cholesterol (387 g/mol).
Which biomarker is most likely intended?
In primary-care lab reports, an mg/dL value is most often glucose, total/LDL/HDL cholesterol, triglycerides, calcium, magnesium, or BUN. Check the test name printed on your lab report.
