What does this tool do?
Different countries report blood glucose in different units. This calculator converts between milligrams per decilitre and millimoles per litre using the standard molecular-weight factor for glucose.
The Formula
mg/dL = mmol/L × 18.0182; mmol/L = mg/dL ÷ 18.0182Frequently Asked Questions
Which unit is used where?
mg/dL is common in the United States, Germany and Japan, while mmol/L is standard in the United Kingdom, Canada, Australia and most of Europe.
Is a converted value a diagnosis?
No. The conversion only changes units. Reference ranges depend on whether the sample was fasting, random or after a meal, and only a clinician can interpret results.
