Estimates based on ADAG data of ∼2,700 glucose measurements over 3 months per A1C measurement in 507 adults with type 1, type 2, and no diabetes. Correlation between A1C and average glucose: 0.92 (42). A calculator for converting A1C results into eAG, in either mg/dl or mmol/l, is available at http://professional.diabetes.org/eAG.
