About this calculator
The HbA1c to average glucose calculator is a useful tool for healthcare professionals and patients with diabetes. It allows converting the glycated hemoglobin (HbA1c) into a measurement of average glucose levels over a period of time.
The formula used by this calculator is the Adams-Garbett equation (eAG), which establishes a linear relationship between HbA1c and average glucose. The formula is: eAG = 28.7·HbA1c − 46.7.
This calculator should be used for informational purposes only and not as a substitute for medical diagnosis or treatment. It is essential to remember that HbA1c is an important marker for assessing long-term glucose control, but it is not a direct measurement of glucose levels at the moment.
