Cholesterol Conversion Formula:
From: | To: |
Cholesterol levels are measured in different units around the world. The conversion between mmol/L (commonly used outside the US) and mg/dL (commonly used in the US) is essential for comparing and interpreting cholesterol values across different measurement systems.
The calculator uses the cholesterol conversion formula:
Where:
Explanation: This conversion factor (38.67) is specific to cholesterol and accounts for the molecular weight and unit conversion between the two measurement systems.
Details: Accurate cholesterol measurement and unit conversion are crucial for assessing cardiovascular risk, making treatment decisions, and comparing research findings across different regions that use different measurement units.
Tips: Enter cholesterol value in mmol/L. The value must be a positive number. The calculator will instantly convert it to mg/dL using the standard conversion factor of 38.67.
Q1: Why is the conversion factor 38.67 for cholesterol?
A: The factor 38.67 is derived from the molecular weight of cholesterol (386.65 g/mol) and the unit conversion between mmol/L and mg/dL.
Q2: Are there different conversion factors for different lipid fractions?
A: Yes, different conversion factors apply to HDL cholesterol (38.67), LDL cholesterol (38.67), and triglycerides (88.57).
Q3: What are normal cholesterol values?
A: Normal total cholesterol is generally <200 mg/dL (5.2 mmol/L), though optimal values vary by individual risk factors.
Q4: When should cholesterol be measured?
A: Cholesterol should be measured fasting for most accurate results, particularly for triglyceride measurement.
Q5: How often should cholesterol be checked?
A: Adults should have cholesterol checked every 4-6 years, or more frequently if risk factors are present.
