Hemoglobin A1c Calculator

About This Tool

This Hemoglobin A1c calculator helps users convert HbA1c percentages into estimated average blood glucose (eAG) levels. It is essential for diabetologists, researchers, and patients wanting to understand their blood sugar control more interpretably.

The tool accepts an HbA1c value, validates the input, and calculates the eAG using the standard formula: eAG (mg/dL) = (28.7 x HbA1c) - 46.7. Users can toggle between mg/dL and mmol/L units for the result, with the mmol/L conversion applying a factor of 0.0555.

Designed for ease of use, the interface includes a simple input box, a units toggle, and a prominent 'Calculate' button. Results are displayed clearly below, with options to copy or switch units quickly. This tool is suitable for clinicians, medical students, and patients aiming for transparent glucose interpretation based on their HbA1c readings.

It supports quick assessments during consultations, research, or personal health tracking, contributing to better understanding and management of diabetes.
