Enter Lipid Values
Formula Used
Main formula:
TG/HDL Ratio = Triglycerides ÷ HDL Cholesterol
For mg/dL values, the entered numbers are divided directly.
For mmol/L values, the calculator first converts each lipid value.
Triglycerides in mg/dL = Triglycerides in mmol/L × 88.57
HDL in mg/dL = HDL in mmol/L × 38.67
Then the converted triglyceride value is divided by converted HDL.

About the Triglyceride HDL Ratio
What This Ratio Shows
The triglyceride to HDL ratio compares two common lipid markers. Triglycerides reflect fat carried in the blood after meals and during storage. HDL is often called protective cholesterol because it helps move cholesterol away from arteries. A lower ratio often suggests better lipid balance. A higher ratio may point toward insulin resistance, metabolic strain, or greater cardiovascular concern. This calculator gives a quick estimate from standard lab values.
Why Unit Conversion Matters
Lipid reports may use mg/dL or mmol/L. These units are not interchangeable without conversion. Triglycerides and HDL use different conversion factors. The calculator converts mmol/L inputs into mg/dL before dividing. This keeps the final ratio consistent. It also helps compare results from different laboratories. Always enter both values from the same report when possible.
Reading the Result
Many people use simple ratio bands for screening. A value below two is often viewed as favorable. A value from two to under three point five may need attention. A value above three point five may require deeper review. These bands are general guides. They do not replace medical judgment. Your age, blood pressure, glucose, family history, smoking status, and medicines matter too. A clinician can interpret the number with your complete profile.
Improving Lipid Balance
Lifestyle choices can influence triglycerides and HDL. Regular activity may lower triglycerides and support HDL. Weight management can improve the ratio for many people. Reducing refined sugar and excess alcohol may also help. Eating fiber rich foods can support better metabolic health. Sleep, stress control, and diabetes care can change lipid patterns. Repeat testing may show whether changes are working. Use this tool to track values over time. Bring saved reports to appointments for clearer discussions. Never stop prescribed treatment without professional advice.
Frequently Asked Questions
What is the triglyceride HDL ratio?
It is triglycerides divided by HDL cholesterol. It gives a simple view of lipid balance and possible metabolic risk. It should be interpreted with other health markers.
Which unit should I choose?
Choose the unit printed on your lab report. Use mg/dL for many United States reports. Use mmol/L for many international reports.
Is a lower ratio better?
Generally, a lower ratio is considered more favorable. However, personal risk depends on many factors, including age, glucose, blood pressure, smoking, and medicines.
Can this calculator diagnose heart disease?
No. It is an educational tool only. It cannot diagnose disease, replace lab interpretation, or replace advice from a qualified healthcare professional.
Should I use fasting or non-fasting results?
Use the fasting status shown on your report. Triglycerides may change after meals. Your clinician can advise which result is best for your situation.
Why does the calculator convert mmol/L?
Triglycerides and HDL have different conversion factors. The calculator converts both values into mg/dL before computing the ratio for consistent comparison.
What does a high ratio mean?
A high ratio may suggest unfavorable lipid balance or metabolic stress. It should be reviewed with other results, symptoms, history, and clinical risk factors.
