Convert HbA1c results across common clinical reporting units. Get tables, exports, formulas, and simple guidance. Built for quick checks, learning, documentation, and daily reference.
| HbA1c (%) | IFCC (mmol/mol) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|---|

| 6.0 | 42 | 126 | 7.0 |
| 7.0 | 53 | 154 | 8.6 |
| 8.0 | 64 | 183 | 10.2 |
| 9.0 | 75 | 212 | 11.8 |
Use these conversion relationships in the calculator.
HbA1c results appear in different formats. That can confuse patients, students, and even staff. Some reports show percent values. Some labs use IFCC mmol/mol. Many people also understand average glucose better. A converter makes these views easier to compare.
HbA1c reflects average glucose exposure over recent weeks. It is not a single reading. It does not move as fast as a fingerstick result. That is why people often pair it with daily glucose records. A good converter helps connect a lab value with a familiar average glucose estimate.
Different regions and labs report HbA1c in different unit systems. The DCCT aligned percent scale is still widely used. The IFCC standard expresses the same idea in mmol/mol. Neither format is more personal or more correct for every setting. They are simply two ways to report the same lab concept.
Estimated average glucose, or eAG, turns HbA1c into a daily style glucose number. This can help when someone understands glucose logs better than percentages. It is still a mathematical estimate. It should not replace direct monitoring. It is best used for education, discussion, and record review.
Conversions are useful, but they do not tell the whole story. Illness, blood disorders, pregnancy, lab methods, and timing can affect interpretation. A conversion tool should support discussion, not replace medical judgment. Keep the original lab report. Compare dates. Review trends instead of one result alone.
Enter one known value. Let the calculator fill the rest. Save the result if you need it for a project, note, or patient education sheet. Use the example table to check common ranges. Read the formula section if you want to verify the math. That makes the tool practical and transparent.
HbA1c estimates average glucose exposure over the past several weeks. It does not show one moment. It reflects long-term glycemic pattern more than a single daily reading.
Some countries, journals, and labs report HbA1c in mmol/mol. Conversion helps you compare reports, educational material, and records without manual calculation.
eAG means estimated average glucose. It translates HbA1c into a glucose-style number that many people find easier to understand in daily discussions.
Not exactly. eAG is a model-based estimate. A meter or sensor average comes from actual readings. They can be close, but they are not always identical.
No. This page is for conversion and education. Diagnosis and treatment decisions should come from a qualified clinician who can review your full situation.
Lab reports and calculators often round numbers for readability. You can change decimal places here to display more detail when needed.
Enter the value you already know from a report or note. Then choose its unit. The calculator will estimate the matching values automatically.
Yes. Use the CSV option for spreadsheet work. Use the PDF option for printing, sharing, or keeping a simple document copy.
