A1C Chart & Calculator
A1C Chart is a comfortable way to understand A1C % result and help relate it to your glucose meter reading.
This A1C chart provides conversion between A1C in % to eAG in mg/dl or mmol/l using the DCCT formula. To use A1C calculator, you need to enter A1C to calculate eAG (BS) and vice versa.
Why do you need an A1C chart?
The A1C result is significant for long-term glucose monitoring. It helps to know, how well or bad your past 3 months blood glucose control. A1C in percentage may be confusing because we measure glucose levels in mg/dl or mmol/l. Converting A1C to equivalent average glucose is easier to interpret.

DCCT formula seems to work best in people with high blood sugars. Because this formula derived from such group.
A1C chart in this article shows the relation between A1C and its BS equivalent, based on the DCCT formula.
Diabetes Control and Complications Trial or DCCT, New England Journal of Medicine 1993; 329:977-986. They studied 1400 T1D; quarterly A1C tests were the primary measure of glycemic control. The study subjects performed quarterly 24-hour, 7-point capillary blood glucose profiles in the home. These are 3 pre-meal tests, 3 post-meal (after 90 minutes) tests, and 1 at bedtime.
Diabetes Care 25:275-278, 2002 result showed a linear relationship between HbA1c and eAG. eAG in mg/dl = (35.6 x HbA1c) - 77.3 or eAG in mmol/l = (1.98 x HbA1c) – 4.29.

Dr. Richard K. Bernstein, the author of the popular book "Diabetes Solution." He is the first who succeeded using low-carb diet for his type-1 diabetes control (with an A1C of 4.2 to 4.6).
Dr. Richard K. Bernstein recommends DCCT's formula to convert A1C to BS. Additionally, our website visitors have preferred DCCT over ADAG formula.
