From A1c to eAG: A Simple Calculator for Your Average Blood Sugar
Understanding your blood sugar levels is critical for managing diabetes and maintaining overall health. Two key metrics used to monitor blood sugar control are A1c and eAG (estimated Average Glucose). This article explains what A1c and eAG are, how they relate, and provides a simple calculator to convert between the two. We'll also cover why these measurements are important and how they can help you stay on track with your health goals.

What is A1c?
The A1c test, also known as the glycated hemoglobin test, measures 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. The higher your blood sugar levels, the more glucose attaches to hemoglobin, resulting in a higher A1c percentage. A1c provides a longer-term view of blood sugar control compared to a single blood glucose reading.
- Normal A1c: Below 5.7%
- Prediabetes A1c: 5.7% to 6.4%
- Diabetes A1c: 6.5% or higher
The A1c target for most adults with diabetes is generally below 7%, but individual targets may vary depending on your age, health conditions, and treatment plan. Discuss your ideal A1c goal with your healthcare provider.
What is eAG (Estimated Average Glucose)?
eAG, or estimated Average Glucose, is a calculated value that represents the average blood sugar level in milligrams per deciliter (mg/dL) over a period of about 2-3 months. It's derived from the A1c test result and provides a way to understand your blood sugar levels in the same units you might see on your blood glucose meter. Many find eAG easier to understand since it’s expressed in the same units as daily glucose readings.
The Relationship Between A1c and eAG
A1c and eAG are directly related. As A1c reflects average blood sugar over time, it can be converted to an equivalent eAG value. This conversion helps patients and healthcare providers to communicate about blood sugar control using a more intuitive number.
A Simple A1c to eAG Conversion Table
Although a calculator is provided later, this quick table offers a convenient reference:
| A1c (%) | eAG (mg/dL) |
|---|---|
| 6 | 126 |
| 7 | 154 |
| 8 | 183 |
| 9 | 212 |
| 10 | 240 |
| 11 | 269 |
| 12 | 298 |
A1c to eAG Calculator
Use this simple method to estimate your eAG from your A1c value.
The formula to estimate eAG (mg/dL) from A1c (%) is:
eAG = (28.7 x A1c) - 46.7
For example, if your A1c is 7%, the estimated average glucose would be:
eAG = (28.7 * 7) - 46.7 = 200.9 - 46.7 = 154.2 mg/dL (approximately 154 mg/dL)
You can also use online calculators readily available, such as the one at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) website. Simply search "A1c to eAG calculator NIDDK" to find it.

Why Are A1c and eAG Important?
Monitoring A1c and eAG is vital for several reasons:
- Diabetes Management: They provide a clear picture of how well your diabetes management plan is working. This helps you and your doctor make informed decisions about medication, diet, and exercise.
- Risk Reduction: Keeping your A1c and eAG within the target range reduces the risk of long-term complications of diabetes, such as heart disease, kidney disease, nerve damage, and eye damage.
- Motivation and Feedback: Tracking these metrics can be motivating. Seeing improvements in your A1c/eAG can reinforce positive lifestyle changes and adherence to your treatment plan.
- Personalized Care: A1c and eAG results help your healthcare provider tailor your treatment plan to meet your specific needs.
Factors That Can Affect A1c Results
It’s essential to be aware that certain factors can influence A1c results, leading to inaccurate readings. These include:
- Anemia: Conditions that affect red blood cell production or lifespan can alter A1c readings.
- Hemoglobin Variants: Certain genetic variations in hemoglobin can interfere with the A1c test.
- Kidney Disease: Kidney disease can sometimes affect A1c levels.
- Pregnancy: A1c levels may be lower during pregnancy.
If you have any of these conditions, discuss with your doctor whether an A1c test is the best way to monitor your blood sugar control. Alternative tests, such as frequent self-monitoring of blood glucose, may be more appropriate.
Lifestyle Changes to Improve Your A1c and eAG
Many lifestyle changes can significantly impact your A1c and eAG levels:
- Diet: Follow a balanced diet that is low in processed foods, sugary drinks, and refined carbohydrates. Focus on whole grains, lean protein, fruits, and vegetables.
- Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week. Regular physical activity helps improve insulin sensitivity and lower blood sugar levels.
- Medication: Take your diabetes medication as prescribed by your doctor. Do not adjust your medication without consulting your healthcare provider.
- Stress Management: Practice stress-reducing techniques such as yoga, meditation, or deep breathing exercises. Stress can raise blood sugar levels.
- Regular Monitoring: Check your blood sugar regularly as advised by your doctor. This helps you understand how different foods and activities affect your blood sugar levels.
- Sleep: Aim for 7-8 hours of quality sleep per night. Poor sleep can negatively affect blood sugar control.
Working with Your Healthcare Provider
Regular communication with your healthcare provider is critical for managing your blood sugar levels effectively. Discuss your A1c and eAG results, any challenges you are experiencing, and any changes you have made to your lifestyle or medication regimen. Your healthcare provider can provide personalized guidance and support to help you achieve your blood sugar goals and reduce your risk of complications.
