how to convert a1c to blood glucose

The A1C test measures your average blood glucose levels over the past 2-3 months. To estimate your average blood glucose (eAG) from your A1C percentage, you can use the following formula:

eAG (mg/dL) = 28.7 × A1C - 46.7

Here’s a quick reference table for common A1C values and their corresponding eAG:

A1C (%) Estimated Average Glucose (mg/dL)

6 126
7 154
8 183
9 212
10 240

This conversion helps you understand how well your blood sugar is being managed over time. However, it’s important to note that this is an estimate and may not account for daily fluctuations in blood sugar levels.
