Convert blood sugar between mg/dL and mmol/L, estimate HbA1c from average glucose and category.
Convert blood sugar between mg/dL and mmol/L, estimate HbA1c from average glucose and category.
Enter values above and click Calculate — results will appear here with the formula explained.
Convert via 18.01559. HbA1c estimates 3-month average: ADAG formula (avg+46.7)/28.7 gives %. Categories: <5.7 normal, 5.7-6.4 prediabetes, ≥6.5 diabetes (diagnosis needs lab).
This is screening, not diagnosis. Home meters vary ±15%. For YMYL diabetes, confirm with lab HbA1c and clinician.
Fasting 100-125 mg/dL is prediabetes range, ≥126 diabetes (repeated).
Convert blood sugar between mg/dL and mmol/L, estimate HbA1c from average glucose and category. Formula: mmol = mg/dL /18.01559. Example: With 126 mg/dL =7.0 mmol/L.

Fasting 100-125 mg/dL is prediabetes range, ≥126 diabetes (repeated).
With 126 mg/dL =7.0 mmol/L. Average 154 mg/dL gives HbA1c ~7.0%, diabetes threshold.
