How to convert A1C to eAG
Enter the lab A1C and choose a glucose unit.
1
Enter the A1C
Use the percentage from a recent laboratory result.
2
Choose the unit
Select mg/dL or mmol/L for the primary result.
3
Compare with logs
Compare the average with meter or sensor data, remembering that the average hides variability.
What does this tool do?
A1C reflects average blood glucose over roughly two to three months. The ADAG equation translates that percentage into an estimated average glucose, which is easier to compare with meter or sensor readings.
The Formula
eAG (mg/dL) = 28.7 × A1C − 46.7; eAG (mmol/L) = eAG (mg/dL) ÷ 18.0182Frequently Asked Questions
What does eAG mean?
Estimated average glucose translates an A1C percentage into the average blood glucose it corresponds to, using the units shown on a meter or sensor.
Can I replace my meter readings with eAG?
No. Averages hide highs and lows. Keep using the monitoring plan your care team recommends and discuss the A1C result with them.
