Diabetes & A1C Calculators
Evidence-based tools validated by ADA clinical standards to help you bridge the gap between lab visits.
A1C to Blood Sugar
The primary clinical standard for converting your HbA1c laboratory percentage into estimated average glucose (eAG) in mg/dL.
Blood Sugar to A1C
Reverse calculate your estimated A1C based on daily glucose meter averages. Essential for between-lab monitoring.
GMI Calculator (CGM)
Calculate your Glucose Management Indicator using average glucose from continuous monitoring systems like Dexcom or Libre.
A1C to mmol/L
Unit converter for international (IFCC) and United States (NGSP) standards. Converts % to mmol/mol and mmol/L.
Time in Range (TIR)
Visualize your percentage of time in the healthy glucose zone (70-180 mg/dL) and its direct correlation to A1C outcomes.
