Blood Sugar ($\text{mg/dL} \leftrightarrow \text{mmol/L}$) & $\text{HbA1c}$ Converter
Convert blood glucose readings between US ($\text{mg/dL}$) and International / UK ($\text{mmol/L}$), plus estimate average glucose ($\text{eAG}$) from $\text{HbA1c}$ percentages.
🟢 Normal Fasting (90 mg/dL = 5.0 mmol/L)
🟡 Prediabetes Fasting (115 mg/dL = 6.4 mmol/L)
🍽️ Post-Meal Goal (140 mg/dL = 7.8 mmol/L)
⚠️ Hypoglycemia (65 mg/dL = 3.6 mmol/L)
🩺 HbA1c Diagnostic Threshold (6.5%)
Input Glucose Reading
Or Enter Glycated Hemoglobin (HbA1c):
Calculates estimated Average Glucose (eAG).
International Value (mmol/L)
5.00 mmol/L
ADA Clinical Classification (Fasting):
Normal Fasting Range (70 - 99 mg/dL)
💡 Molar Mass Conversion Math:
$$\text{Glucose } \text{C}_6\text{H}_{12}\text{O}_6 = 180.156\text{ g/mol} \implies 1\text{ mmol/L} = 18.0182\text{ mg/dL}$$
Understanding Blood Sugar Units & HbA1c Relationship
Blood glucose concentration is measured globally in two distinct scientific formats:
- mg/dL (Milligrams per Deciliter): Standard unit in the United States, Japan, France, and Israel.
- mmol/L (Millimoles per Liter): Standard unit in the United Kingdom, Canada, Australia, and most European nations.
- The ADAG Formula (HbA1c ↔ eAG): $$\text{eAG (mg/dL)} = 28.7 \times \text{HbA1c} - 46.7$$ $$\text{eAG (mmol/L)} = 1.59 \times \text{HbA1c} - 2.59$$
