Cholesterol Units Converter
Convert cholesterol and triglyceride values between mg/dL and mmol/L for total cholesterol, HDL, LDL, and triglycerides.
Why Convert Cholesterol Units?
Lipid panels are reported in mg/dL in the United States and mmol/L in Canada and many European countries. Converting between the two helps you compare lab reports, research papers, and clinical guidelines. Pair this with the Cholesterol Ratio Calculator when you need ratio-based risk context.
Conversion Factors
Total cholesterol, HDL, and LDL convert with a factor of 0.02586 from mg/dL to mmol/L (multiply by 38.67 for the reverse). Triglycerides use 0.01129 and 88.57 because they have a different molecular weight basis.
Example Conversion
A total cholesterol of 200 mg/dL equals about 5.172 mmol/L. An LDL of 2.8 mmol/L equals about 108.28 mg/dL using the same cholesterol factor.
Frequently Asked Questions
Which lipids share the same conversion factor?
Total cholesterol, HDL, and LDL all use the same mg/dL to mmol/L multiplier. Triglycerides require a separate factor.
How do I convert mg/dL to mmol/L for LDL?
Multiply the mg/dL value by 0.02586. For example, 100 mg/dL LDL is about 2.586 mmol/L.
How do I convert mmol/L to mg/dL?
Multiply mmol/L by 38.67 for cholesterol fractions or by 88.57 for triglycerides.
Can I convert triglycerides here?
Yes. Choose the triglycerides option before entering your value so the correct factor is applied.
