A1c Calculator: Convert Your A1c to Average Blood Sugar (eAG)
Understanding your blood sugar levels is crucial for managing diabetes or prediabetes. The A1c test provides a snapshot of your average blood sugar over the past 2-3 months. But what does that A1c number actually mean in terms of your daily blood sugar levels? That's where an A1c calculator comes in handy! This article will explain what A1c is, how to convert it to estimated average glucose (eAG), and provide a handy A1c calculator for quick conversions.
What is A1c?
The A1c test, also known as the hemoglobin A1c, HbA1c, or glycated hemoglobin test, measures the percentage of your red blood cells that have glucose attached to them. Higher A1c levels indicate higher average blood sugar levels over the past 2-3 months. This is because glucose in your bloodstream binds to hemoglobin, the protein in red blood cells that carries oxygen. The more glucose in your blood, the more glucose binds to hemoglobin.
A1c is expressed as a percentage. Here's a general guideline:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
It's important to note that these are general guidelines. Your doctor might have specific A1c targets based on your individual health circumstances.
What is eAG (Estimated Average Glucose)?
Estimated Average Glucose (eAG) is an estimate of your average blood sugar level in milligrams per deciliter (mg/dL), based on your A1c result. It's a more familiar way to understand your A1c, as most people are accustomed to monitoring their blood sugar in mg/dL. Think of it as translating your A1c percentage into a more relatable blood sugar value.
Why Convert A1c to eAG?
Converting A1c to eAG helps you:
- Better Understand Your Blood Sugar Control: Seeing your average blood sugar in mg/dL makes it easier to visualize how your diet, exercise, and medications are affecting your blood sugar levels.
- Track Progress More Effectively: Monitoring eAG alongside your A1c allows for a more comprehensive picture of your blood sugar management.
- Communicate More Clearly with Your Healthcare Team: eAG can be a useful tool when discussing your diabetes management plan with your doctor.

|---|---|---|
| 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 |

Factors That Can Affect A1c
Several factors can affect your A1c reading, even if your average blood sugar levels are stable. These include:
- Anemia: Certain types of anemia can falsely lower A1c readings.
- Kidney Disease: Kidney disease can interfere with the production of red blood cells, affecting A1c results.
- Hemoglobin Variants: Certain genetic hemoglobin variants can affect the accuracy of the A1c test.
- Pregnancy: Pregnancy can sometimes affect A1c levels.
- Certain Medications: Some medications can impact red blood cell turnover and, therefore, A1c levels.
It is vital to discuss any medical conditions or medications you are taking with your doctor, as these can influence the interpretation of your A1c results.
How to Lower Your A1c

If your A1c is high, your doctor will work with you to develop a plan to lower it. This plan may include:
- Dietary Changes: Focusing on a balanced diet with controlled carbohydrate intake can help regulate blood sugar levels.
- Regular Exercise: Physical activity improves insulin sensitivity and helps lower blood sugar.
- Medications: Your doctor may prescribe medications to help lower your blood sugar. Common medications include metformin, sulfonylureas, and insulin.
- Monitoring Your Blood Sugar: Regularly checking your blood sugar with a blood glucose meter helps you understand how your body responds to different foods and activities.
The Importance of Regular A1c Testing
Regular A1c testing is crucial for managing diabetes and prediabetes. It provides a long-term view of your blood sugar control, allowing you and your doctor to make informed decisions about your treatment plan. The frequency of A1c testing will depend on your individual circumstances, but typically, people with diabetes should have their A1c checked at least twice a year, and those with poorly controlled diabetes may need to be tested more frequently.
