About A1C Calculator

This A1C calculator estimates your hemoglobin A1C percentage based on your average blood sugar levels over a specified time period. A1C reflects your average blood glucose control over the past 2-3 months.

What is A1C?

Hemoglobin A1C (HbA1c) is a blood test that measures the percentage of hemoglobin that is coated with sugar. It provides an average of your blood sugar levels over the past 2-3 months, giving healthcare providers insight into your long-term glucose control.

A1C Formula:

The calculator uses the ADA (American Diabetes Association) formula:
A1C = (Average Blood Sugar + 46.7) ÷ 28.7
This formula converts average blood sugar in mg/dL to A1C percentage.

A1C Target Ranges:

Normal (No Diabetes):

  • A1C: <5.7%
  • Average Blood Sugar: <117 mg/dL

Prediabetes:

  • A1C: 5.7% - 6.4%
  • Average Blood Sugar: 117-137 mg/dL

Diabetes:

  • A1C: ≥6.5%
  • Average Blood Sugar: ≥137 mg/dL

Well Controlled Diabetes:

  • A1C: <7.0%
  • Average Blood Sugar: <154 mg/dL

Important Notes:

  • A1C testing should be done every 3-6 months for diabetes management
  • Individual A1C targets may vary based on age, health conditions, and other factors
  • Some conditions (anemia, kidney disease) can affect A1C accuracy
  • Laboratory A1C testing is more accurate than estimates from blood sugar averages
  • Work with your healthcare team to set personalized A1C goals
  • Regular blood sugar monitoring helps track daily control between A1C tests
