Enter the GMI and the constant values into the calculator to determine the A1C level.

Gmi To A1C Formula

The following formula is used to calculate the A1C level from GMI (Glucose Management Indicator).

A1C = (GMI + 2.59) / 1.59


  • A1C is the estimated average glucose level (%) GMI is the Glucose Management Indicator (mg/dL)

To calculate the A1C level, add 2.59 to the GMI value, then divide the result by 1.59. The result is the estimated average glucose level, or A1C.

What is a Gmi To A1C?

A Gmi to A1C is a conversion that translates the average glucose levels in the blood, known as Glucose Management Indicator (GMI), into an A1C value. A1C is a common test used to diagnose and manage diabetes, as it provides an average of blood glucose levels over the past 2-3 months. The GMI to A1C conversion allows healthcare providers to estimate a patient’s A1C levels based on their continuous glucose monitoring (CGM) data.

How to Calculate Gmi To A1C?

The following steps outline how to calculate the GMI to A1C using the given formula:

  1. First, determine the GMI value (mg/dL).
  2. Add 2.59 to the GMI value.
  3. Divide the sum by 1.59.
  4. Finally, you will get the A1C value (%).

Example Problem:

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

GMI = 150 mg/dL

Let’s calculate the A1C value:

Step 1: GMI = 150 mg/dL

Step 2: GMI + 2.59 = 150 + 2.59 = 152.59

Step 3: (GMI + 2.59) / 1.59 = 152.59 / 1.59 = 96.05

Therefore, the estimated average glucose level (A1C) is 96.05%.
