Blood Sugar Unit Converter

About Blood Sugar Unit Conversion

Blood sugar levels are measured in two main units: milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). The mg/dL unit is commonly used in the United States, while mmol/L is more prevalent in other countries. This converter allows you to easily switch between these two units for accurate blood glucose monitoring and international comparisons.

Conversion Formula

To convert between mg/dL and mmol/L, use the following formulas:

  • mg/dL to mmol/L: Divide mg/dL by 18
  • mmol/L to mg/dL: Multiply mmol/L by 18
