Understanding Glucose Units
mg/dL (milligrams per deciliter) is commonly used in the United States and measures the weight of glucose in a specific volume of blood.
mmol/L (millimoles per liter) is used in most other countries and measures the molar concentration of glucose in blood.
The conversion factor is: 1 mmol/L = 18 mg/dL
