The US, Germany and a few others report blood glucose in milligrams per deciliter (mg/dL); most of the world uses millimoles per litre (mmol/L). The exact relationship is mmol/L = mg/dL ÷ 18.0182 (the molar mass of glucose). For example 100 mg/dL ≈ 5.6 mmol/L, and a fasting level of 126 mg/dL (7.0 mmol/L) is the diabetes threshold.
This is a unit conversion for convenience and education — it is not a diagnosis. Always interpret readings with your clinician and meter's guidance.
Quick reference — 1 Milligram/deciliter (mg/dL) is equal to:
