Conversion Formula:
| From: | To: |
LDL (Low-Density Lipoprotein) cholesterol, often called "bad cholesterol," is a type of lipoprotein that carries cholesterol to tissues. High levels of LDL cholesterol are associated with increased risk of cardiovascular diseases.
The conversion formula between mmol/L and mg/dL for LDL cholesterol is:
This conversion factor (38.67) is derived from the molecular weight of cholesterol and is standardized for clinical use.
Details: Different countries use different measurement systems for cholesterol levels. The United States typically uses mg/dL, while many other countries use mmol/L. Conversion between these units is essential for international research, clinical practice, and patient understanding when reviewing lab results from different healthcare systems.
Tips: Enter your LDL cholesterol value in mmol/L. The calculator will automatically convert it to mg/dL using the standard conversion factor. Values must be non-negative numbers.
Q1: Why is the conversion factor 38.67?
A: This factor is based on the molecular weight of cholesterol (386.7 g/mol). The conversion is calculated as: mg/dL = mmol/L × molecular weight ÷ 10.
Q2: What are optimal LDL cholesterol levels?
A: Generally, LDL levels below 100 mg/dL (2.6 mmol/L) are considered optimal for most adults, though targets may vary based on individual risk factors.
Q3: Is the conversion factor the same for all cholesterol measurements?
A: Yes, the same conversion factor (38.67) applies to total cholesterol, LDL cholesterol, and HDL cholesterol when converting between mmol/L and mg/dL.
Q4: How often should cholesterol be checked?
A: Most adults should have their cholesterol checked every 4-6 years. Those with risk factors for heart disease may need more frequent testing.
Q5: Are there any limitations to this conversion?
A: The conversion is mathematically precise, but clinical interpretation should always consider the specific context and other risk factors.
