HbA1c to eAG Calculator for Average Glucose Conversion
Quickly convert HbA1c (%) values to estimated Average Glucose (eAG). This calculator helps laboratories and clinicians translate HbA1c results into an easily understandable average glucose value for better clinical interpretation.
See how your calculated HBA1c appears in a real, clinician-ready lab report.
This HbA1c to eAG calculator is intended for reference purposes only and does not replace professional medical judgment, laboratory protocols, or clinical evaluation.
How the HbA1c to eAG Calculation Works
This calculator uses a clinically validated formula derived from the ADAG (A1c-Derived Average Glucose) study.
The calculation requires:
- HbA1c value expressed as a percentage (%)
Formula Used (HbA1c to eAG)
For eAG in mg/dL:
If eAG needs to be displayed in mmol/L:

Frequently Asked Questions About HbA1c to eAG Calculator
The calculator uses the ADAG study-derived formula: eAG (mg/dL) = (28.7 � HbA1c) - 46.7.
eAG converts HbA1c percentages into estimated average glucose values that are easier for patients to understand and compare with daily glucose readings.
HbA1c reflects long-term glucose exposure as a percentage, while eAG converts it into estimated average glucose values in mg/dL or mmol/L.
Normal eAG values generally correspond to HbA1c values below 5.7%. Elevated eAG levels may indicate poor glycemic control.
Diagnostic laboratories, diabetologists, endocrinologists, and clinicians commonly use HbA1c to eAG calculators for diabetes monitoring and reporting.
Yes. The calculator supports both mg/dL and mmol/L reporting formats for regional flexibility.
Yes. The ADAG-derived equation is clinically validated for consistent HbA1c to eAG conversion.
Yes. MocDoc LIMS automates HbA1c to eAG conversion during report generation, helping laboratories standardize diabetes reporting workflows.
