Home > Resources > A1C conversion chart
This is the internet's only exhaustive A1C to glucose (eAG) conversion chart. While the most common A1C levels are likely between 4 and 15, we've decided to include values from 1 to 20 in the interest of creating a truly exhaustive list.
For reference the formula for converting A1C to glucose mg/dl is 28.7 x A1C β 46.7. Similarly, the formula for converting A1C to glucose mmol/l is (28.7 x A1C β 46.7) / 18.
