1. What Is Glucose Unit Conversion?

Glucose unit conversion between mmol/L (millimoles per liter) and mg/dL (milligrams per deciliter) is essential for interpreting blood glucose levels across different measurement systems used worldwide.

2. How Does The Calculator Work?

The calculator uses the standard conversion formula:

Where:

• \( mmol/L \) — Glucose concentration in millimoles per liter
• \( mg/dL \) — Glucose concentration in milligrams per deciliter
• \( 18 \) — Conversion factor based on molecular weight of glucose

Explanation: The conversion factor of 18 is derived from the molecular weight of glucose (C₆H₁₂O₆ = 180 g/mol) and unit conversion between liters and deciliters.

3. Importance Of Glucose Unit Conversion

Details: Different countries use different measurement systems for blood glucose. The United States primarily uses mg/dL, while most other countries use mmol/L. Accurate conversion is crucial for proper diabetes management and international medical communication.

4. Using The Calculator

Tips: Enter glucose value in mmol/L and click "Convert" to get the equivalent value in mg/dL. The conversion works for any valid glucose measurement (≥0 mmol/L).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 18?
A: The factor 18 comes from glucose's molecular weight (180 g/mol) divided by 10 (to convert from liters to deciliters).

Q2: What are normal blood glucose ranges?
A: Fasting: 3.9-5.6 mmol/L (70-100 mg/dL); 2 hours post-meal: <7.8 mmol/L (<140 mg/dL).

Q3: Which countries use which units?
A: mmol/L: UK, Canada, Australia, Europe; mg/dL: United States, Japan, Egypt, Colombia.

Q4: Is the conversion factor exact?
A: The factor 18.018 is often rounded to 18 for practical clinical use, providing sufficient accuracy for medical purposes.

Q5: Can I convert mg/dL back to mmol/L?
A: Yes, use the reverse formula: mmol/L = mg/dL ÷ 18.
