Cholesterol Conversion Calculator

Helps you convert cholesterol (TC, HDL, LDL) and triglyceride measurements from mmol/L to mg/dL and the other way around.

Refer to the text below the cholesterol converter for more information about the conversions between the two measurement units.


With two difference measurement systems, mmol/L in the UK and mg/dL in Europe and USA, clinicians may be required to convert cholesterol levels from one unit to the other.


For Total Cholesterol, HDL cholesterol and LDL cholesterol:

  • To get from mmol/L to mg/dL multiply by 38.66976;
  • To get from mg/dL to mmol/L multiply by 0.02586.

For Triglycerides:

  • To get from mmol/L to mg/dL multiply by 88.57396;
  • To get from mg/dL to mmol/L, multiply by 0.01129.

Cholesterol Conversion Formulas

In Europe or USA cholesterol and triglyceride levels are expressed in mg/dL whilst in the UK, they are usually expressed in mmol/L.

For Total Cholesterol, HDL cholesterol and LDL cholesterol

  • To convert from mmol/L to mg/dL multiply by 38.66976;
  • To convert from mg/dL to mmol/L multiply by 0.02586.

For Triglycerides

  • To convert from mmol/L to mg/dL multiply by 88.57396;
  • To convert from mg/dL to mmol/L, multiply by 0.01129.

Cholesterol levels are tested through blood cholesterol or lipid panel tests, and are recommended every 5 years between the ages of 20 and 45 and after more frequently.

The relation between the different forms of cholesterol provides information about cardiovascular risk, therefore not only the levels are measured but also the TC/HDL ratio and the LDL/HDL ratio.
