Monitoring blood sugar levels is essential for managing diabetes and overall metabolic health. Our Blood Sugar Converter tool helps you easily convert between different glucose measurement units (mg/dL and mmol/L) and understand what your levels mean for your health.
How to Use the Blood Sugar Converter
Enter Your Glucose Value: Input your current blood sugar reading in the provided field.
Select the Unit: Choose whether your measurement is in mg/dL (common in the US) or mmol/L (international standard).
Choose Measurement Context: Indicate whether your reading was taken while fasting, post-meal (2 hours after eating), or at a random time.
Click “Convert”: The tool will instantly convert your reading and provide a health status assessment.
Understanding Your Results
The converter displays:
mg/dL and mmol/L values – Your reading in both measurement units.
Health Status – Whether your level is normal, prediabetic, or diabetic based on medical guidelines.
Reference Chart – A visual comparison of your reading against standard ranges.
Reference Table – A detailed breakdown of healthy and at-risk glucose levels.
Why Blood Sugar Conversion Matters
Different countries use different units for blood glucose measurements:
mg/dL (milligrams per deciliter) – Commonly used in the United States.
mmol/L (millimoles per liter) – Used in most other countries, including Canada, the UK, and Australia.
Our converter ensures you can interpret your results accurately, no matter which unit your glucose meter uses.
Blood Sugar Level Guidelines
Fasting Blood Sugar (Before Eating)
Normal: 70–99 mg/dL (3.9–5.5 mmol/L)
Prediabetes: 100–125 mg/dL (5.6–6.9 mmol/L)
Diabetes: 126 mg/dL (7.0 mmol/L) or higher
Post-Meal Blood Sugar (2 Hours After Eating)
Normal: Below 140 mg/dL (7.8 mmol/L)
Prediabetes: 140–199 mg/dL (7.8–11.0 mmol/L)
Diabetes: 200 mg/dL (11.1 mmol/L) or higher
Random Blood Sugar (Any Time)
Normal: Below 140 mg/dL (7.8 mmol/L)
Possible Prediabetes: 140–199 mg/dL (7.8–11.0 mmol/L)
Likely Diabetes: 200 mg/dL (11.1 mmol/L) or higher
Important Notes
Blood sugar levels fluctuate based on diet, activity, and individual health factors.
A single reading does not confirm a diagnosis—consult a doctor for medical advice.
People with diabetes should follow their healthcare provider’s personalized targets.
Use our Blood Sugar Converter to track and understand your glucose levels better. Regular monitoring helps in early detection and effective management of diabetes and metabolic health.
