1. What is Glucose Unit Conversion?

Glucose concentration in blood can be measured in different units - grams per liter (g/L) or millimoles per liter (mmol/L). This calculator converts between these units using the molecular weight of glucose.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• 180 — Molecular weight of glucose (g/mol)
• 1000 — Conversion factor from moles to millimoles

Explanation: The formula converts mass concentration (g/L) to molar concentration (mmol/L) using glucose's molecular weight.

3. Importance of Glucose Measurement

Details: Accurate glucose measurement is essential for diagnosing and managing diabetes mellitus. Different countries and laboratories may report results in different units, making conversion necessary.

4. Using the Calculator

Tips: Enter glucose concentration in g/L. The calculator will automatically convert it to mmol/L. Normal fasting blood glucose is about 0.7-1.1 g/L (3.9-6.1 mmol/L).

5. Frequently Asked Questions (FAQ)

Q1: Why is the molecular weight of glucose 180?
A: Glucose (C₆H₁₂O₆) has a molecular weight of 180 g/mol (C=12, H=1, O=16; 6×12 + 12×1 + 6×16 = 180).

Q2: What's the difference between g/L and mmol/L?
A: g/L measures mass concentration while mmol/L measures molar concentration, which accounts for the number of molecules.

Q3: Which units are more commonly used?
A: mmol/L is standard in most countries, while g/L is sometimes used in France and a few other places.

Q4: Does this conversion work for other substances?
A: No, this is specific to glucose. Other substances have different molecular weights.

Q5: How precise is this conversion?
A: The conversion is mathematically exact, but actual measurement precision depends on laboratory methods.
