Convert blood glucose levels from mg/dL to mmol/L
Medical Disclaimer: This tool is for informational purposes only and should not replace professional medical advice. Always consult with a healthcare provider for medical decisions.
Conversion factor: 1 mg/dL = 0.0555 mmol/L (divide by 18)
| Category | mg/dL | mmol/L |
|---|---|---|
| Low (Hypoglycemia) | < 70 | < 3.9 |
| Normal (Fasting) | 70 - 99 | 3.9 - 5.5 |
| Prediabetes (Fasting) | 100 - 125 | 5.6 - 6.9 |
| Diabetes (Fasting) | ≥ 126 | ≥ 7.0 |
Divide the mg/dL value by 18. For example, 100 mg/dL ÷ 18 = 5.56 mmol/L.
Different countries and medical systems use different units. The US uses mg/dL, while most other countries use mmol/L (International System of Units).
Contact your healthcare provider immediately if you have abnormal blood glucose readings. Do not make medical decisions based solely on this converter.
