Understanding Blood Sugar Levels
Blood glucose (sugar) levels are measured in two different units depending on your location. In the United States, mg/dL (milligrams per deciliter) is commonly used, while most other countries use mmol/L (millimoles per liter).
The conversion formula is simple: mg/dL ÷ 18 = mmol/L (or multiply mmol/L by 18 to get mg/dL). This calculator makes it easy to convert between these two measurement systems.
Regular blood sugar monitoring is essential for people with diabetes or prediabetes. Understanding your levels and what they mean helps you make informed decisions about diet, exercise, and medication.
