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 4.0 and 15.0, we've decided to include values from 1.0 to 20.0 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 – 46.7. Similarly, the formula for converting A1C to glucose mmol/l is (28.7 x A1C – 46.7) / 18.
