what units are blood sugar measured in

Blood sugar levels are typically measured in two units:

• Milligrams per deciliter (mg/dL): This is the most common unit used in the United States.
• Millimoles per liter (mmol/L): This unit is commonly used in many other countries, including Canada and the UK.

For example, a normal fasting blood sugar level is generally between 70-100 mg/dL or 3.9-5.6 mmol/L.

Here’s a quick conversion table:

mg/dL mmol/L

70 3.9
100 5.6
126 7.0
200 11.1

Always refer to your healthcare provider for the correct interpretation of your blood sugar levels.
