Convert your HbA1c between % and mmol/mol, see your estimated average blood sugar (eAG), and what your result means — instantly and free.
| HbA1c (%) | HbA1c (mmol/mol) | Category |
|---|---|---|
| Below 5.7% | Below 39 | Normal |
| 5.7% – 6.4% | 39 – 47 | Pre-diabetes |
| 6.5% or higher | 48 or higher | Diabetes |
Reference ranges are for diagnosis in non-pregnant adults. If you already have diabetes, your personal target (often below 7.0% / 53 mmol/mol) is set by your doctor. Always compare against the range printed on your own lab report.
Upload your lab report to MedVault and see your HbA1c trend across every test — with each value explained in plain language.

Subtract 2.15 from the percentage and multiply by 10.929. For example, 6.5% equals 48 mmol/mol and 7.0% equals 53 mmol/mol. To go the other way, divide the mmol/mol value by 10.929 and add 2.15.
eAG converts your HbA1c into an estimated average blood sugar in the same units as a home glucometer. The formula is eAG (mg/dL) = 28.7 × HbA1c% − 46.7. An HbA1c of 7.0% is roughly an average glucose of 154 mg/dL (8.6 mmol/L).
Normal HbA1c is below 5.7% (39 mmol/mol). Pre-diabetes is 5.7% to 6.4% (39 to 47 mmol/mol). Diabetes is diagnosed at 6.5% (48 mmol/mol) or higher, confirmed on a repeat test.
