This calculator converts cholesterol units from the popularly used mg/dL to the SI units mmol/L. It works for total serum cholesterol, high-density lipoproteins (HDL), low-density lipoproteins (LDL), and triglycerides.

Converting cholesterol levels measurement units by yourself can be overwhelming, so read on to understand how our cholesterol calculator works and what unit cholesterol is measured in.

It looks like you just had your cholesterol levels checked. If you're interested in using them to assess your heart disease risks and general health condition, check out our cholesterol ratio calculator.

The American Heart Association (AHA) recommends that all adults age 20 or older have their cholesterol checked every four to six years and work with their healthcare providers to determine their risk for cardiovascular disease and stroke.

How to use cholesterol units converter

The cholesterol units converter assists in converting cholesterol values from milligrams per deciliter (mg/dL) to millimoles per liter (mmol/L) for distinct lipid profile components, including total serum cholesterol, HDL (high-density lipoprotein), LDL (low-density lipoprotein), and triglycerides.

Here's a step-by-step guide on how to use the tool:

  1. Select the specific lipid profile component you intend to convert, such as total serum cholesterol, HDL, LDL, or triglycerides (use the second section of the calculator for these).

  2. Input the value in either the first or second field based on your preference, whether you want to convert from mg/dL to mmol/L or vice versa. Alternatively, you can seamlessly switch between units of measurement.

  3. That concludes the process! The calculator will handle the conversion for you, ensuring a rapid and accurate outcome.

For instance, consider a scenario in which you have a total serum cholesterol value of 200 mg/dL and wish to convert it to mmol/L using the cholesterol units converter. If you input the value 200 into the first field of the Total serum cholesterol, HDL, or LDL group, the calculator will provide an equivalent value of 5.172 mmol/L.

What unit is cholesterol measured in?

The typical measurement units for cholesterol levels is milligrams per deciliter (mg/dL).

Millimoles per liter (mmol/L) is the standard medical unit for measuring concentrations of substances in the blood. Canada and some European countries use this unit.

Various publications use either one or the other unit, and it can be confusing to understand the guidelines. Our cholesterol calculator is here to help you.

How do I convert mmol/L to mg/dL?

  • To convert cholesterol units of TC (total cholesterol), HDL (high-density lipoprotein), and LDL (low-density lipoprotein) from mmol/L to mg/dL, you need to multiply by 38.67.

  • To convert cholesterol units of TG (triglycerides) from mmol/L to mg/dL, you need to multiply by 88.57.

How do I convert mg/dL to mmol/L?

  • To convert cholesterol units of TC (total cholesterol), HDL (high-density lipoprotein), and LDL (low-density lipoprotein) from mg/dL to mmol/L, you need to multiply by 0.02586.

  • To convert cholesterol units of TG (triglycerides) from mg/dL to mmol/L, you need to multiply by 0.01129.

What is my LDL level in mg/dL if it is 2.8 mmol/L?

The answer is 108.28 mg/dL. This is because the conversion factor from mmol/L to mg/dL for LDL equals 38.67, so we have 2.8 × 38.67 = 108.28. The same method works for HDL and total cholesterol (TC).
