A1C to Glucose Converter (eAG)
Convert between A1C percentage and estimated average glucose.
Two ways of expressing the same thing
The A1C test reflects average blood glucose over roughly the past few months, reported as a percentage, and it can also be expressed as an estimated average glucose in the units used for everyday readings. This converts between the two, so a figure in one form makes sense in the other.
Enter an A1C or an average glucose to convert between them.
A conversion, not an interpretation
This is a straightforward conversion between two representations of the same underlying measure, and nothing more — it does not interpret what a value means or what should be done about it. A1C and glucose levels, what ranges mean, and any decisions about diabetes management are matters for you and a healthcare professional who knows your situation, and they carry real medical weight. Use the conversion to translate a figure between the percentage and average-glucose forms, or between glucose units, when comparing information across sources. This is general information, not medical advice; interpretation and management of these values belong with a qualified healthcare professional.
