GMI to A1C Calculator

Input either GMI (Glucose Management Indicator) or A1C (Estimated Average Glucose Level) to calculate the missing value based on the established relationship between these metrics.

The GMI to A1C Calculator allows you to easily convert between the Glucose Management Indicator (GMI) in mg/dL and the A1C percentage.

This is especially useful for individuals managing diabetes, as it bridges the gap between average glucose readings and long-term glucose control. The calculator provides accurate estimations to help monitor and plan diabetes management.

Formula

GMI to A1C

$\text{GMI (mg/dL)} = (\text{A1C} \times 1.59) – 2.59$

A1C to GMI

$\text{A1C (\%)} = \frac{\text{GMI} + 2.59}{1.59}$

Variable	Description	Unit
GMI	Glucose Management Indicator	mg/dL
A1C	Estimated Average Glucose Level (glycated hemoglobin)	% (Percentage)

Solved Calculations

Example 1: Calculate GMI from A1C

Step	Value	Explanation
A1C	7.0%	Input value
Formula	$\text{GMI} = (\text{A1C} \time$	Substitute values
Calculation	$(7.0 \times 1.59) –$	Final GMI result

Example 2: Calculate A1C from GMI

Step	Value	Explanation
GMI	9.5 mg/dL	Input value
Formula	$\text{A1C} = \frac{\text{GMI} + 2$	Substitute values
Calculation	$(9.5 + 2.59) /$	Final A1C result
