Triglycerides mg/dL to mmol/L Converter

How it is calculated

Triglyceride results are converted with a single fixed factor of 88.57, used in both directions:

mmol/L = mg/dL ÷ 88.57
mg/dL = mmol/L × 88.57

Pick the direction first: the default is mg/dL to mmol/L, and the other option converts mmol/L to mg/dL. The output is rounded to two decimals and carries the target unit. The factor is specific to triglycerides; cholesterol uses a different one (about 38.67), so do not reuse this tool for HDL, LDL or total cholesterol. The tool performs no clinical judgement and does not flag high or low values, and it also accepts a negative number without complaint, so check that your entry is a real measurement.

Common mistakes

• Choosing the wrong direction. A value of 150 entered with mmol/L to mg/dL selected becomes 13,285.50 mg/dL, an impossible figure, so confirm which unit your report uses first.
• Using the glucose or cholesterol factors. Glucose uses about 18 and cholesterol about 38.67; triglycerides use 88.57 because of their different molecular weight.
• Expecting a round result. 150 mg/dL is 1.69 mmol/L, not exactly 1.7; the displayed 1.7 in guidelines is a rounded figure.
• Typing the unit or other text into the value box, such as 150 mg/dL. Only a plain number is accepted, and anything else returns nothing.
• Converting a lipid value that was reported as a ratio or as non-HDL cholesterol. Only a triglyceride concentration converts with this factor.
