A1c to eAG Conversion: Easily Translate Your A1c to Average Blood Sugar
Understanding your blood sugar levels is crucial, especially if you're managing diabetes. The A1c test is a common way to measure your average blood sugar over the past 2-3 months. But what does that A1c number actually mean in terms of your day-to-day glucose levels? That's where the estimated Average Glucose (eAG) comes in. This article will guide you through the A1c to eAG conversion, making it easy to understand your diabetes management.
What is A1c?
The A1c test, also known as hemoglobin A1c, glycated hemoglobin, or HbA1c, provides a snapshot of your average blood sugar levels over the past 2-3 months. It works by measuring the percentage of your red blood cells that have glucose attached to them. Higher A1c levels indicate higher average blood sugar levels, which increases the risk of diabetes complications. It is essential for diabetes management.
- Why is A1c important? It helps you and your healthcare provider assess how well your blood sugar has been controlled over time.
- How often should I get an A1c test? Typically, your doctor will recommend A1c testing every 3-6 months, depending on your diabetes management plan.
- What is a normal A1c? For people without diabetes, a normal A1c is generally below 5.7%. The target A1c for people with diabetes is often below 7%, but this can vary based on individual factors.
What is eAG (Estimated Average Glucose)?
The estimated Average Glucose (eAG) is a direct translation of your A1c value into an average blood sugar level (in mg/dL or mmol/L). It gives you a more tangible idea of what your A1c means in terms of your daily glucose readings. Many find the eAG easier to relate to because it mirrors the numbers they see on their blood glucose meters.
- Why use eAG? It helps bridge the gap between the A1c result and the blood sugar readings you take at home.
- Is eAG the same as my daily glucose readings? No, eAG is an estimate of your average blood sugar. Your actual daily readings will fluctuate based on food intake, activity, medication, and other factors.
- How is eAG calculated? It is calculated using a formula derived from large studies correlating A1c and average glucose levels.
The A1c to eAG Conversion Formula
The most common formula to convert A1c to eAG (in mg/dL) is:
eAG (mg/dL) = (28.7 x A1c) - 46.7
To convert A1c to eAG in mmol/L:
eAG (mmol/L) = (1.59 x A1c) - 2.59
While you can use these formulas manually, online A1c to eAG converters are readily available to simplify the process.
A1c to eAG Conversion Chart
Here's a helpful chart illustrating common A1c levels and their corresponding eAG values (mg/dL and mmol/L):
| A1c (%) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|
| 6.0 | 126 | 7.0 |
| 6.5 | 140 | 7.8 |
| 7.0 | 154 | 8.6 |
| 7.5 | 169 | 9.4 |
| 8.0 | 183 | 10.2 |
| 8.5 | 197 | 11.0 |
| 9.0 | 212 | 11.8 |
| 9.5 | 226 | 12.6 |
| 10.0 | 240 | 13.4 |
How to Use A1c and eAG for Diabetes Management
Knowing your A1c and its eAG equivalent allows you to:
- Set realistic blood sugar goals: Working with your doctor, you can use your eAG as a guide for your daily blood sugar targets.
- Monitor the effectiveness of your treatment plan: If your A1c and eAG are higher than your target range, you may need to adjust your medication, diet, or exercise routine.
- Stay motivated: Seeing the connection between your A1c, eAG, and daily blood sugar readings can empower you to make positive lifestyle changes and stick to your diabetes management.
- Communicate better with your healthcare provider: Being able to understand and discuss both A1c and eAG helps you have more informed conversations about your diabetes care.

It's important to remember that both A1c and eAG have limitations:
- They are averages: They don't show the full picture of your blood sugar fluctuations. You can have good A1c and eAG values but still experience dangerous highs and lows.
- Certain conditions can affect A1c accuracy: Anemia, kidney disease, and some hemoglobinopathies can alter A1c results, making them unreliable.
- eAG is an estimate: It's not a precise measurement of your average glucose. Your actual average blood sugar might be slightly different.

Because of these limitations, it is still important to frequently monitor your blood sugar levels and work with a healthcare professional.
Conclusion
Converting your A1c to estimated Average Glucose (eAG) can provide a clearer understanding of your blood sugar control and aid in diabetes management. By utilizing the conversion formula or the chart, you can better relate your A1c results to your day-to-day glucose levels. However, always remember that A1c and eAG are just tools, and it's essential to work with your healthcare provider to develop a comprehensive diabetes management plan. Keeping your blood sugar levels under control is essential for preventing diabetes complications.
