Enter the average glucose level into the calculator to determine the A1C level. This calculator can also evaluate any of the variables given the others are known.

## Average Glucose To A1C Formula

The following formula is used to calculate the A1C level from average blood glucose level.

A1C = (AG + 46.7) / 28.7

Variables:

- A1C is the estimated Average Glucose level (%) AG is the Average Glucose level (mg/dL)

To calculate the A1C level, add 46.7 to the average glucose level, then divide the result by 28.7. The result is the estimated A1C level.

## What is the Average Glucose To A1C?

Average Glucose to A1C is a measure used to determine a person’s average blood glucose levels over a period of two to three months. The A1C test, also known as the HbA1c, glycated hemoglobin, or glycohemoglobin test, is an important tool in managing diabetes. It reflects the average blood sugar levels by measuring the percentage of hemoglobin, a protein in red blood cells, that is coated with sugar. The higher the A1C level, the poorer the blood sugar control and the higher the risk of diabetes complications.

## How to Calculate Average Glucose To A1C?

The following steps outline how to calculate the Average Glucose to A1C ratio.

- First, determine the Average Glucose level (AG) in mg/dL.
- Next, use the formula A1C = (AG + 46.7) / 28.7 to calculate the estimated A1C level.
- Finally, the result will be the estimated Average Glucose level (A1C) in percentage (%).

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

Average Glucose level (AG) = 150 mg/dL
