Cholesterol HDL, LDL, Triglycerides Ratio Calculator (SI Version in mmol/L)

This SI version in mmol per liter is for folks outside the United States! In case you were curious I just took the US mg/dL limits for all the numbers and just divided by 38.66 which is the conversion factor. So a US cholesterol number of 200 mg/dL is the same as a SI cholesterol number of 200/38.66 = 5.17 mmol/L.

UPDATE: I just found out that triglycerides use a different ratio, namely 88.5 so I will have to work that into my calculation now!

Enter any three of the following numbers and the calculator will find the fourth missing value, and then it will tell you the ratios and how good they are. You can read the article from the Mayo Clinic on desired levels here. The articles on the Total Cholesterol/HDL and HDL/LDL ratios from eMedTV can be found here and here, and the article on triglycerides over HDL ratio is here.


Total Cholesterol mmol/L
HDL (High density lipoprotein) mmol/L
LDL (Low density lipoprotein) mmol/L
Triglycerides mmol/L
