Summary
Enter HbA1c (%) or eAG (mg/dL or mmol/L) to get the converted value and diabetes management interpretation.
How it works
- Enter your HbA1c percentage in the HbA1c field, or enter an eAG value in mg/dL or mmol/L.
- The tool applies the ADA formula: eAG (mg/dL) = 28.7 × HbA1c − 46.7.
- Results show eAG in both mg/dL and mmol/L alongside your HbA1c value.
- The interpretation tier (normal, prediabetes, or diabetes) is displayed based on HbA1c thresholds.
- The reference table at the bottom lists common HbA1c values with their eAG equivalents.
Use cases
- Understand what your HbA1c lab result means in everyday blood sugar terms.
- Convert a continuous glucose monitor average back to an estimated HbA1c.
- Compare glucose management across different units (mg/dL vs mmol/L).
- Educate patients on the relationship between HbA1c and daily average glucose.
