Enter the value in mmol/L and select the lipid type to convert cholesterol or triglycerides to mg/dL using the appropriate laboratory conversion factor.

Cholesterol mmol/L to mg/dL Converter

Enter a value in mmol/L and choose the lipid type to calculate the equivalent value in mg/dL.

Cholesterol mmol/L to mg/dL Formula

The following formula is used to convert most cholesterol values from mmol/L to mg/dL.

mg/dL = mmol/L × 38.67

For triglycerides, laboratories use a different conversion factor.

mg/dL = mmol/L × 88.57

Variables:

  • mg/dL is the value in milligrams per deciliter
  • mmol/L is the value in millimoles per liter
  • 38.67 is the conversion factor for total, LDL, HDL, and non-HDL cholesterol
  • 88.57 is the conversion factor for triglycerides

To calculate the result in mg/dL, multiply the mmol/L value by the correct factor for the selected lipid type.

What is Cholesterol mmol/L to mg/dL Conversion?

Cholesterol tests may be reported in either mmol/L or mg/dL depending on the country, laboratory, or medical guideline being used. Total cholesterol, LDL cholesterol, HDL cholesterol, and non-HDL cholesterol all use the same standard conversion factor of 38.67. Triglycerides are different because of their molecular properties, so they use a factor of 88.57. Converting between these units makes it easier to compare lab reports, reference ranges, and treatment targets across different systems.

How to Convert Cholesterol mmol/L to mg/dL?

The following steps outline how to convert cholesterol mmol/L to mg/dL.


  1. First, determine the measured value in mmol/L.
  2. Next, identify the lipid type as total cholesterol, LDL, HDL, non-HDL, or triglycerides.
  3. Multiply the mmol/L value by 38.67 for cholesterol values or by 88.57 for triglycerides.
  4. After calculating the result, verify your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Total Cholesterol = 5.2 mmol/L

Conversion Factor = 38.67

Result = 5.2 × 38.67 = 201.08 mg/dL

Cholesterol mmol/L to mg/dL Conversion Table

The table below shows example conversions for a 5 mmol/L measurement using the correct factor for each lipid parameter.

Analyte Factor (mg/dL per mmol/L) 5 mmol/L in mg/dL
Total Cholesterol 38.67 193.35 mg/dL
LDL Cholesterol 38.67 193.35 mg/dL
HDL Cholesterol 38.67 193.35 mg/dL
Non-HDL Cholesterol 38.67 193.35 mg/dL
Triglycerides 88.57 442.85 mg/dL

For example, 3.0 mmol/L of LDL cholesterol is equal to 116.01 mg/dL, while 1.7 mmol/L of triglycerides is equal to 150.57 mg/dL. These conversions are commonly used to compare lipid results across different lab reporting systems.
