About Blood Sugar Units

Blood sugar is commonly measured in:

  • mg/dL (milligrams per decilitre) – often used in the United States.
  • mmol/L (millimoles per litre) – used in the UK and most of Europe.

Conversion formula: 1 mmol/L = 18 mg/dL.

Monitoring your blood sugar regularly can support better health and diabetes management.
