How 100 mg/dL of glucose converts to mmol/L
Glucose is the simple sugar that circulates in blood; fasting glucose is reported on routine metabolic panels. Glucose is reported in mg/dL on U.S., Japanese, and some German reports, and in mmol/L on UK, Canadian, Australian, and most European reports.
The conversion factor used here is 0.05551. Glucose has a molecular weight of 180.16 g/mol, giving the familiar factor 0.05551 (often written as dividing by 18 for the reverse direction). Applied here: 100 mg/dL × 0.05551 = 5.551 mmol/L.
