mg/dL to mg/L Converter
Convert milligrams per deciliter to milligrams per liter instantly
mg/dL
mg/L
Conversion Formula
mg/L = mg/dL × 10
mg/dL = mg/L ÷ 10
The conversion between mg/dL and mg/L is straightforward because these units measure concentration or density. Since 1 deciliter equals 0.1 liters, multiplying a value in mg/dL by 10 gives you the equivalent in mg/L.

Conversion Examples
Example 1: Converting 85 mg/dL to mg/L
Step 1: Take the value in mg/dL: 85
Step 2: Multiply by 10: 85 × 10 = 850
Result: 85 mg/dL = 850 mg/L
Example 2: Converting 120 mg/dL to mg/L
Step 1: Take the value in mg/dL: 120
Step 2: Multiply by 10: 120 × 10 = 1,200
Result: 120 mg/dL = 1,200 mg/L
Example 3: Converting 2,500 mg/L to mg/dL
Step 1: Take the value in mg/L: 2,500
Step 2: Divide by 10: 2,500 ÷ 10 = 250
Result: 2,500 mg/L = 250 mg/dL
Common Medical Applications
Both mg/dL and mg/L are concentration units frequently used in medical laboratories and healthcare settings. The mg/dL unit is predominantly used in the United States for reporting various blood test results, while mg/L is more common in other regions.
| Test Parameter | Typical Range (mg/dL) | Equivalent (mg/L) |
|---|---|---|
| Blood Glucose (Fasting) | 70-100 | 700-1,000 |
| Total Cholesterol | <200 | <2,000 |
| LDL Cholesterol | <100 | <1,000 |
| HDL Cholesterol | >40 (men), >50 (women) | >400 (men), >500 (women) |
| Triglycerides | <150 | <1,500 |
| Creatinine | 0.7-1.3 | 7-13 |
| Blood Urea Nitrogen | 7-20 | 70-200 |
Important Note: Reference ranges may vary between laboratories and depend on individual factors such as age, gender, and health status. Always consult with healthcare professionals for interpretation of your specific test results.

Frequently Asked Questions
What is the difference between mg/dL and mg/L?
The primary difference is the volume measurement used. mg/dL measures milligrams per deciliter (100 milliliters), while mg/L measures milligrams per liter (1,000 milliliters). Since 1 liter contains 10 deciliters, a value in mg/L is always 10 times larger than the same concentration expressed in mg/dL.
How do I convert mg/dL to mg/L?
Multiply the mg/dL value by 10 to get mg/L. For example, 85 mg/dL × 10 = 850 mg/L. This is because one liter equals ten deciliters, so the concentration per liter is ten times the concentration per deciliter.
Why are different units used for the same measurement?
Different countries and medical systems have historically adopted different units. The United States predominantly uses mg/dL for reporting blood test results, while many other countries use mg/L or mmol/L. Both units provide the same health-related data, just expressed differently.
Is mg/dL the same as g/L?
No, these are different units. 1 g/L equals 100 mg/dL because one gram equals 1,000 milligrams, and one liter equals 10 deciliters. To convert mg/dL to g/L, divide by 100. To convert g/L to mg/dL, multiply by 100.
Which unit is more accurate?
Neither unit is inherently more accurate than the other. They are simply different ways of expressing the same concentration. Accuracy depends on the measurement method and laboratory equipment, not the unit of expression. Both mg/dL and mg/L can represent measurements to the same degree of precision.
Can I use this conversion for all substances?
Yes, the conversion factor of 10 applies universally when converting between mg/dL and mg/L, regardless of the substance being measured. This is a simple volume conversion and does not depend on the chemical properties of the substance.
How is this different from converting to mmol/L?
Converting from mg/dL to mmol/L is more complex and requires knowing the molecular weight of the specific substance. Each substance has a different conversion factor. For example, glucose uses a factor of 0.0555, while cholesterol uses 0.0259. The mg/dL to mg/L conversion is simpler and always uses the factor of 10.
Where are mg/dL measurements commonly used?
mg/dL is the standard unit in the United States for reporting blood glucose, cholesterol, triglycerides, creatinine, and many other blood test parameters. It is routinely used in American medical laboratories, hospitals, and clinical settings.
