A1C Conversion Chart and Calculator

Your A1C test result (also known as HbA1c or glycated hemoglobin) can be a good gauge of your diabetes control because it provides an estimated average blood glucose level over the past few months.

Unlike daily blood glucose test results, which are reported as mg/dL, A1C is often reported as a percentage, which can make it difficult to understand the relationship between the two values.

A1C (%)	eAG (mg/dL)	eAG (mmol/L)	GMI (%)	Status	Comments
4.0	68	3.8	5.4	Below normal	May indicate hypoglycemia risk
5.0	97	5.4	6.4	Normal	Excellent control
5.5	111	6.2	6.8	Normal	Good control
6.0	126	7.0	7.2	Normal high	Monitor closely
6.5	140	7.8	7.6	Diabetes threshold	Treatment may be needed
7.0	154	8.6	8.0	Diabetes	Common treatment target
7.5	169	9.4	8.4	Above target	Treatment adjustment may be needed
8.0	183	10.2	8.8	High	Increased complication risk
8.5	197	11.0	9.2	Very high	Urgent action needed
9.0	212	11.8	9.6	Very high	High complication risk
9.5	226	12.6	10.0	Extremely high	Immediate action required
10.0	240	13.4	10.4	Extremely high	Critical level

Note: Use this information to become more familiar with the relationship between A1C and eAG values and help improve discussion of glucose control with your doctor. Never use it as a basis for changing your disease management on your own.
