HbA1c Converter
Your HbA1c result can be shown as a percentage, in mmol/mol, or as an estimated average glucose level — different labs use different units. Enter your value to convert it instantly between all three and understand what your number really means.

How to use
- Type your HbA1c value in the box (for example 7.0).
- Choose the unit your lab used: percent (%), mmol/mol, or estimated average glucose.
- The result updates live, and the equivalent values in all other units appear below.
Good to know
- Percent (%) is the older DCCT unit; mmol/mol is the newer IFCC unit — most labs print one of them.
- The average-glucose estimate is a guide only, not a replacement for daily sugar readings.
- Always discuss your HbA1c result with your doctor; targets differ for each person.
Note: Estimate only — not medical advice. eAG formula: 28.7 x A1c minus 46.7 (ADAG study). Actual average sugar can differ for each person.
