Understand the method, inputs and limits behind your result.
- Formula
- Glucose(mmol/L) = glucose(mg/dL) / 18.016. Reverse conversion multiplies by 18.016.
- Variables
- Convert: mg/dL → mmol/L, mmol/L → mg/dL
- Value
- Units
- Use the units shown beside each input. Counts and ratios are dimensionless unless labeled otherwise.
- Example
- 100 mg/dL equals 5.55 mmol/L, and 7.0 mmol/L equals 126 mg/dL, the fasting threshold for diabetes.
- Assumptions
- Glucose: 1 mmol/L = 18.016 mg/dL. Diagnostic thresholds follow the ADA Standards of Care; confirm a diagnosis with a repeat test.

Methodology & References
The method depends on the selected model and input options. Review the assumptions and references above before interpreting the result.
- Choose mg/dL to mmol/L or the reverse.
- Enter your glucose reading.
- Read the converted value and fasting category.
Interpretation and limitations
- How do I convert mmol/L to mg/dL? Multiply by 18 (18.016 exactly). To go from mg/dL to mmol/L, divide by 18.
- Is the category valid after a meal? No. The normal, prediabetes and diabetes bands shown apply to fasting glucose only.
