Glucose Conversion Formula:
From: | To: |
The conversion between mg/dL (milligrams per deciliter) and mmol/L (millimoles per liter) is essential in medical contexts, particularly for blood glucose measurements. Different countries and medical systems use different units, making accurate conversion crucial for proper diagnosis and treatment.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor 18.018 is derived from the molecular weight of glucose (C₆H₁₂O₆), which is approximately 180.18 g/mol. Dividing by 10 converts deciliters to liters, resulting in the factor 18.018.
Details: Accurate unit conversion is vital for healthcare professionals and patients to interpret blood glucose levels correctly, especially when comparing results from different regions or medical devices that may use different measurement units.
Tips: Enter the glucose value in mg/dL. The value must be a positive number. The calculator will automatically compute and display the equivalent value in mmol/L.
Q1: Why is the conversion factor 18.018?
A: The factor comes from glucose's molecular weight (180.18 g/mol) divided by 10 to convert deciliters to liters.
Q2: Are mg/dL and mmol/L used interchangeably?
A: No, they are different units. mg/dL is common in the US, while mmol/L is standard in most other countries.
Q3: What is a normal blood glucose level?
A: Normal fasting glucose is typically 70-100 mg/dL (3.9-5.6 mmol/L). Values may vary slightly between different guidelines.
Q4: Can I convert mmol/L back to mg/dL?
A: Yes, multiply mmol/L by 18.018 to get mg/dL.
Q5: Is this conversion specific to glucose?
A: Yes, this conversion factor is specific to glucose. Other substances have different conversion factors based on their molecular weights.
