1. What is LDL-C Conversion?

LDL-C (Low-Density Lipoprotein Cholesterol) conversion between mmol/L and mg/dL is necessary for comparing cholesterol values across different measurement systems used in various countries and medical contexts.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( \text{LDL-C (mmol/L)} \) — LDL cholesterol value in millimoles per liter
• \( 38.67 \) — Conversion factor from mmol/L to mg/dL

Explanation: This conversion allows healthcare professionals and patients to translate LDL cholesterol values between the two most commonly used measurement units worldwide.

3. Importance of LDL-C Conversion

Details: Accurate LDL-C conversion is essential for proper interpretation of cholesterol levels, treatment decisions, and international comparison of cardiovascular risk assessment data.

4. Using the Calculator

Tips: Enter LDL cholesterol value in mmol/L. The value must be a positive number. The calculator will automatically convert it to mg/dL using the standard conversion factor.

5. Frequently Asked Questions (FAQ)

Q1: Why convert LDL-C from mmol/L to mg/dL?
A: Different countries use different measurement units. The US typically uses mg/dL while many other countries use mmol/L, making conversion necessary for international comparisons.

Q2: Is the conversion factor exact?
A: The conversion factor 38.67 is derived from the molecular weight of cholesterol and provides a clinically accepted standard conversion.

Q3: What are normal LDL-C values?
A: Optimal LDL-C is generally below 100 mg/dL (2.6 mmol/L), though targets may vary based on individual cardiovascular risk factors.

Q4: Can I convert mg/dL back to mmol/L?
A: Yes, to convert mg/dL to mmol/L, divide the mg/dL value by 38.67.

Q5: Are there different conversion factors for other cholesterol measurements?
A: Yes, total cholesterol and HDL cholesterol use the same conversion factor, while triglycerides use a different conversion factor (88.57).
