Overview

Convert total, HDL, or LDL cholesterol and triglycerides between mg/dL and mmol/L using analyte-specific conversion factors. Enter a value, select the analyte and source and target units, then choose the desired decimal precision. This tool is for reference and is not medical advice.

When to use

Convert a cholesterol result from mg/dL to mmol/L for SI-unit reporting.
Convert triglycerides from mmol/L to mg/dL when comparing laboratory results.
Check equivalent total, HDL, or LDL cholesterol values with a selected number of decimal places.

How it works

1Enter the cholesterol or triglyceride value.
2Select Total Cholesterol, HDL Cholesterol, LDL Cholesterol, or Triglycerides.
3Choose the source unit and target unit: mg/dL or mmol/L.
4Set decimal places if needed and review the JSON conversion result.

Use cases

Laboratory professionals can compare lipid results reported in conventional and SI units.
Clinicians and cardiology teams can translate total, HDL, LDL, and triglyceride values between reporting systems.
Researchers and students can verify unit equivalents using analyte-specific factors and consistent rounding.

Examples

1. Convert total cholesterol to mmol/L

Laboratory professional

Background

A lipid result is reported as 200 mg/dL, but the receiving report uses mmol/L.

Problem

Find the equivalent total cholesterol concentration in mmol/L.

How to use

Enter 200 as the value, select Total Cholesterol, choose mg/dL as the source unit and mmol/L as the target unit, and keep Decimal Places at 2.

{"value":200,"analyte":"total","sourceUnit":"mgdl","targetUnit":"mmol","decimalPlaces":2}

Outcome

The result is 5.17 mmol/L, using the cholesterol factor 0.02586.

2. Convert triglycerides to mg/dL

Clinical data analyst

Background

A triglyceride result is recorded as 2.8 mmol/L and needs to be compared with a report using mg/dL.

Problem

Convert the triglyceride concentration without applying the cholesterol factor.

How to use

Enter 2.8 as the value, select Triglycerides, choose mmol/L as the source unit and mg/dL as the target unit, and use 2 decimal places.

FAQ

Which analytes can I convert?
