A1C to eAG & eAG to A1C Calculator

The A1C to eAG & eAG to A1C Calculator is an important tool often used by both people with diabetes and healthcare professionals. This calculator helps you easily understand the relationship between A1C and average blood glucose (eAG) values.

Important notice: Please discuss this supplementary information with your actual healthcare professionals to better understand your overall diabetes management plan. The calculation is for informational purposes and should not be used to make treatment decisions or changes.

What is A1C?

The A1C test measures your average blood glucose levels over the last 2-3 months. Also known as haemoglobin A1C, this test shows how much sugar in your blood is bound to your red blood cells. Your A1C is expressed as a percentage. It plays an important role in diabetes management and is an indicator of how well people with diabetes are controlling their blood glucose.

What is eAG?

eAG refers to your average blood glucose level and is measured in mg/dL (milligrams per deciliter). It helps you better understand your blood glucose management by converting your A1C test results to eAG, which is a unit closer to your daily blood glucose readings.

A1C to eAG Conversion

The formula used to convert your A1C value to an average blood glucose level (eAG) can be expressed as follows: eAG (mg/dL) = 28.7 × A1C - 46.7

This formula allows you to convert the A1C percentage to a value in mg/dL, which you may be more familiar with daily blood glucose measurements.

eAG to A1C Conversion

The formula used to convert your average blood glucose level (eAG) to A1C percentage can be expressed as follows: A1C = (eAG + 46.7) / 28.7
