how to convert blood sugar to a1c

To estimate your A1C level based on your average blood sugar levels, you can use the following formula or reference table:

Formula:

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

Reference Table:

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

126 6.0
154 7.0
183 8.0
212 9.0
240 10.0
269 11.0
298 12.0

This conversion is an estimate and should not replace a laboratory A1C test. For accurate results, consult your healthcare provider.
