what unit is blood sugar measured in

Blood sugar levels are typically measured in two units:

• Milligrams per deciliter (mg/dL): Commonly used in the United States.
• Millimoles per liter (mmol/L): Commonly used in many other countries.

For example, a normal fasting blood sugar level is generally between 70-99 mg/dL or 3.9-5.5 mmol/L. Always refer to your healthcare provider for specific target ranges based on your health condition.
