Where these factors come from
Glucose (C6H12O6, molar mass 180.156 g/mol) converts at 1 mmol/L = 18.016 mg/dL. Note that other substances have their own molar masses — this converter is specific to glucose.

Common questions
Why is the factor 18.016?
Glucose has a molar mass of 180.156 g/mol. Converting mmol/L to mg/dL multiplies by molar mass ÷ 10, which is 18.0156 — rounded here to 18.016.
Is 7 mmol/L high?
This site converts units, not diagnoses. For context, 7 mmol/L is 126 mg/dL, a figure clinicians commonly associate with diabetes thresholds — check with a clinician.
Does the same factor work for cholesterol?
No. Cholesterol has a different molar mass (386.65 g/mol), so its mmol/L ↔ mg/dL factor is about 38.7. Use a substance-specific converter.
