A1C chart on this page has A1C to BS conversion chart and calculator using the DCCT formula. To use this A1C calculator; you have to enter A1C/BS to calculate the BS/A1C equivalent.
Why do you need a hemoglobin A1C chart?
The hemoglobin A1C result is an important value for long-term glucose monitoring; about three months mean value of glucose level. HbA1C results are in percentage value. This may be confusing for many, because we are measuring plasma glucose levels in mg/dl or mmol/l using a glucose monitor. Converting A1C to equivalent blood-glucose level (as shown by the glucometer) can be easier interpreting the result.

DCCT (The Diabetes Control and Complications Trial) Formula: Below is the a1c chart to show a relation between A1C and BS equivalent. This A1C chart is based on the DCCT formula, a randomized clinical trial designed to compare intensive and conventional therapies and their relative effects on the development and progression of diabetic complications in patients with type 1. Seven-point capillary blood-glucose profiles (pre-meal, post-meal, and bedtime) obtained in the DCCT were analyzed to define the relationship between HbA1c and BG. This DCCT formula seems to work a lot better in people with very high blood sugars.
Mean plasma glucose = (a1c x 35.6)–77.3 mg/dl (or) (a1c x 1.98)–4.29 mmol/l

Dr. Richard K. Bernstein, the author of the popular book "Diabetes Solution," is the first who successfully used low-carb diet for his type-1 diabetes control (with an A1C of 4.2 to 4.6). He recommends DCCT's formula to convert A1C to BS than the formula by ADAG recommended by ADA. We trust Dr. Richard K. Bernstein recommendation over American Diabetes Association (ADA). Additionally, our website visitors have preferred DCCT to ADAG formula.
