can you calculate a1c from average blood sugar

Yes, you can estimate your A1C level from your average blood sugar using the following formula:

A1C (%) = (Average Blood Sugar (mg/dL) + 46.7) / 28.7

For example, if your average blood sugar is 154 mg/dL, your estimated A1C would be:

A1C = (154 + 46.7) / 28.7 ≈ 7.0%

Here’s a quick reference table:

Average Blood Sugar (mg/dL) Estimated A1C (%)

126 6.0
154 7.0
183 8.0
212 9.0
240 10.0

This formula provides an estimate and may not be as accurate as a lab test. Always consult your healthcare provider for precise A1C measurements and interpretation.
