Cholesterol Units Converter

To calculate your cholesterol ratio in mmol/L, you just have to make sure both values – total cholesterol and HDL-cholesterol – are in the same units. Then you divide the total cholesterol number by HDL cholesterol level:

Cholesterol ratio in mmol/L = Total cholesterol (mmol/L)/HDL-cholesterol (mmol/L)

Conversion for TC (total cholesterol), HDL (high-density lipoprotein), and LDL (low-density lipoprotein)

• To get from SI units (mmol/L) to mg/dL multiply by 38.67.
• To get from mg/dL to SI (in mmol/L) multiply by 0.02586.

The conversion factors are

• For total, HDL and LDL cholesterols: 1 mmol/liter = 38.6698 mg/dL
• For triglycerides: 1 mmol/liter = 88.5740 mg/dL

Cholesterol Levels measurement units

• Cholesterol is typically measured in 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.
