Divide the mg/dL value by 18. For example, a glucose level of 100 mg/dL is about 5.6 mmol/L. To go back, multiply mmol/L by 18. The converter does this automatically — just type a number into either field.
For cholesterol, divide the mg/dL value by 38.67. For example, 200 mg/dL is about 5.2 mmol/L. Triglycerides use a different factor — 88.57.
Converting from mass (mg/dL) to amount of substance (mmol/L) depends on the molecular weight of the substance. Glucose, cholesterol, triglycerides and creatinine all have different molecular weights, so the factors differ.
The US and a few other countries usually report results in mg/dL, while most of Europe, Canada, Australia and many other countries use mmol/L or µmol/L. The converter helps compare results from different labs.
No. Reference ranges are shown for general context and vary by lab and method. Always discuss your lab results with a doctor.
