The A1C Calculator is a free online tool designed to convert between hba1c and estimated average glucose (eag) values in mg/dl or mmol/l, with diabetes risk classification. It allows you to perform these calculations quickly and accurately without manual computations.

Select the conversion direction (A1C to glucose or glucose to A1C), choose your glucose unit (mg/dL or mmol/L), then enter the relevant value. The calculator instantly converts and classifies your result as Normal, Prediabetes, or Diabetes. Once you enter these values, the calculator will automatically compute and display the results instantly.

The A1C Calculator uses the following formula to calculate your results: eAG (mg/dL) = 28.7 × A1C − 46.7\neAG (mmol/L) = eAG (mg/dL) ÷ 18.0182\nA1C = (eAG (mg/dL) + 46.7) ÷ 28.7\n\nSource: ADAG (A1C-Derived Average Glucose) Study This formula is standard and widely accepted for these types of calculations.

Sure! Here is a practical example: An HbA1c of 7.0% corresponds to an estimated average glucose (eAG) of 154 mg/dL (8.6 mmol/L), which falls in the Diabetes range (A1C ≥ 6.5%). This example demonstrates how the inputs are processed through the formula to yield the final results.

To use the A1C Calculator, you need to enter: Conversion Direction, Glucose Unit, HbA1c Value, Glucose Value (eAG). These inputs help the tool calculate precise results tailored to your situation.

The A1C Calculator outputs the following details: HbA1c, eAG (mg/dL), eAG (mmol/L), Health Category. This comprehensive breakdown helps you understand the different aspects of the calculated figures.
