What is HbA1c?
HbA1c, or glycated hemoglobin, is a measure of your average blood sugar over the past 2 to 3 months. It reflects how much glucose is attached to your red blood cells. The higher your HbA1c, the higher your average blood sugar — and your risk of complications from diabetes.
Why Convert HbA1c to Average Blood Sugar?
While HbA1c is a standard marker used in medical labs, most people find it easier to understand their average blood sugar in mg/dL — the unit used by glucose meters. Converting your HbA1c into an estimated average glucose gives you a clearer picture of your daily blood sugar control.
How to Use the Calculator
Enter your HbA1c value in the input box (e.g., 6.3).
Click “Calculate” to get your estimated average blood sugar.
Instantly view your blood sugar in mg/dL along with a brief interpretation.
This calculator is based on the widely accepted formula:
Estimated Average Glucose (mg/dL) = (28.7 × HbA1c) – 46.7
Understanding Your Results
Once you enter your HbA1c value, the calculator provides both the numerical result and a health interpretation:
| HbA1c Level (%) | Interpretation |
|---|---|
| Below 5.7% | Normal |
| 5.7% – 6.4% | Prediabetes |
| 6.5% and above | Diabetes |
Use this as a guide, but always consult your healthcare provider for a complete evaluation.
