What is the difference between mmol/L and mg/dL?

mmol/L (millimoles per liter) measures molar concentration — the number of molecules per liter of solution. This is the SI standard used in most countries worldwide. mg/dL (milligrams per deciliter) measures mass concentration — the weight of substance per deciliter. This unit is primarily used in the United States.

Why does the conversion factor differ between substances?

The conversion factor is derived from the molecular weight of each substance. Since different molecules have different masses, converting between molar concentration (mmol/L) and mass concentration (mg/dL) requires substance-specific factors. The formula is: mg/dL = mmol/L × (molecular weight ÷ 10).

Which countries use mmol/L vs mg/dL?

mmol/L is used in most countries following the SI system, including the UK, Canada, Australia, New Zealand, and most of Europe, Asia, and Africa. mg/dL is primarily used in the United States.

How do I convert mmol/L to mg/dL manually?

Multiply the mmol/L value by the appropriate conversion factor: 18.018 for blood glucose, 38.67 for cholesterol, or 88.57 for triglycerides. Example: 5.5 mmol/L blood glucose × 18.018 = 99.1 mg/dL.

Are these conversion factors exact?

Yes, the conversion factors are based on precise molecular weights and are considered accurate for clinical purposes. The factor 18.018 for blood glucose is derived from the exact molecular weight of glucose (180.156 g/mol).

Can I use this converter for medical decisions?

This converter provides accurate unit conversions based on established molecular weights and clinical standards. However, it is intended for reference and educational purposes only. Medical decisions should always be made in consultation with qualified healthcare professionals.

Triglycerides mmol/L to mg/dL: Complete Conversion Guide

Convert triglycerides from mmol/L to mg/dL with the 88.57 conversion factor. Includes quick tables, clinical categories, and fasting lipid panel context.

Quick Answer

To convert triglycerides from mmol/L to mg/dL, multiply by 88.57.

mmol/L	mg/dL	Common Category
1.0	89	Normal
1.7	151	Borderline High
2.3	204	High
5.6	496	High, near very high
5.7	505	Very High

Use the triglycerides option in the converter. Triglycerides use a different conversion factor from cholesterol, LDL, and HDL. Do not use the cholesterol factor of 38.67 for triglycerides.

Key Takeaways

Summary:

Point Fact
Conversion factor 1 mmol/L = 88.57 mg/dL
Reverse formula mg/dL ÷ 88.57 = mmol/L
Common normal cutoff Below 150 mg/dL, about below 1.7 mmol/L
Very high cutoff 500 mg/dL or higher, about 5.7 mmol/L or higher
Interpretation Triglycerides are interpreted as part of a lipid panel, not as a diagnosis by themselves

Point	Fact
Conversion factor	1 mmol/L = 88.57 mg/dL
Reverse formula	mg/dL ÷ 88.57 = mmol/L
Common normal cutoff	Below 150 mg/dL, about below 1.7 mmol/L
Very high cutoff	500 mg/dL or higher, about 5.7 mmol/L or higher
Interpretation	Triglycerides are interpreted as part of a lipid panel, not as a diagnosis by themselves

Triglycerides Conversion Formula

Triglycerides are measured in two common unit systems:

mmol/L: millimoles per liter, common in countries using SI units.
mg/dL: milligrams per deciliter, common in the United States.

The conversion used on this site is:

Direction	Formula
mmol/L to mg/dL	mmol/L × 88.57
mg/dL to mmol/L	mg/dL ÷ 88.57

The factor is different from cholesterol because triglycerides are a different class of molecules. This site uses 88.57 for triglycerides and 38.67 for total cholesterol, LDL, and HDL.

Triglycerides Categories

The following categories are commonly used in patient education and lipid panel interpretation.

Category	mg/dL	mmol/L
Normal	< 150	< 1.7
Borderline High	150-199	1.7-2.2
High	200-499	2.3-5.6
Very High	≥ 500	≥ 5.7

These ranges describe triglyceride concentration. They do not diagnose a condition by themselves. Clinicians interpret triglycerides together with LDL, HDL, total cholesterol, medical history, medications, and cardiovascular risk.

Fasting vs. Non-Fasting Triglycerides

Triglycerides can change after meals. A lipid panel may be fasting or non-fasting depending on the clinical situation and local practice.

Test Context	What It Means
Fasting lipid panel	Measured after a fasting period requested by a clinician or lab
Non-fasting lipid panel	Measured without fasting; triglycerides may be influenced by recent food intake
Repeat testing	May be used when a value needs confirmation or clinical follow-up

If your result was not fasting, use the converted value as a unit conversion only. Ask your healthcare provider how to interpret it.

Triglycerides vs. Cholesterol Conversion

Choose table format

Marker	Conversion Factor	Example
Triglycerides	mmol/L × 88.57	1.7 mmol/L = 151 mg/dL
Total Cholesterol	mmol/L × 38.67	5.2 mmol/L = 201 mg/dL
LDL Cholesterol	mmol/L × 38.67	2.6 mmol/L = 101 mg/dL
HDL Cholesterol	mmol/L × 38.67	1.6 mmol/L = 62 mg/dL

This difference is why a triglycerides converter should not reuse the cholesterol conversion factor.

FAQ

What is the triglycerides mmol/L to mg/dL formula?

Use mg/dL = mmol/L × 88.57.

For example, 1.7 mmol/L × 88.57 = 150.6 mg/dL, usually rounded to 151 mg/dL.

Is 1.7 mmol/L triglycerides normal?

1.7 mmol/L is approximately 151 mg/dL. That is around the common borderline high cutoff for triglycerides.

What is 2.3 mmol/L triglycerides in mg/dL?

2.3 mmol/L equals 203.7 mg/dL, usually rounded to 204 mg/dL.

What is 5.7 mmol/L triglycerides in mg/dL?

5.7 mmol/L equals 504.8 mg/dL, usually rounded to 505 mg/dL. This is around the common very high triglycerides cutoff.

Why is triglycerides conversion different from cholesterol?

Triglycerides and cholesterol are different substances. Triglycerides use the 88.57 factor, while total cholesterol, LDL, and HDL use 38.67.

Can this page interpret my lipid panel?

No. This page converts units and explains common reference categories. A lipid panel should be interpreted by a qualified healthcare professional.
