Conversion Chart
Blood glucose is measured in milligrams per deciliter (mg/dL) in the United States, and millimoles per liter (mmoles/L) in many other countries (Canada, England, Australia) This is important to remember if you are talking with someone from a country who uses a different measurement system than you do.
- The conversion factor is about 18.
-
- Divide the U.S. value by 18 to get the European value (mg/dl / 18 = mmol/L).
-
- Multiply the European value by 18 to get the U.S. value (mmol/L x 18 = mg/dl).
-
- Example: In the U.S., a bg of 100 mg/dL is about the same as 5.6 mmol/L. Here's a chart to help you.
