mg/L ⇄ mg/dL Conversion Calculator
How to Use This Calculator
Using this tool to convert mg/l to mg/dl is fast and straightforward. We designed the interface to be intuitive for both medical professionals and patients.
First, select the specific lab substance you are checking from the dropdown menu. While the conversion math for these units is consistent, selecting the substance helps you verify your test type.
Next, choose your conversion direction. The default setting converts from mg/L to mg/dL, but you can switch it if you need the reverse calculation.
Finally, enter your numeric value into the input field. The calculator will instantly display the accurate result and the specific formula used for the math.
mg/L vs mg/dL: What is the Difference?
Understanding the difference between mg/l vs mg/dl comes down to volume. Both units measure the concentration of a substance in a liquid, such as blood or urine.
The unit “mg/L” stands for milligrams per liter. It represents how many milligrams of a substance are present in one full liter of fluid.
The unit “mg/dL” stands for milligrams per deciliter. A deciliter is one-tenth of a liter.
Because a deciliter is a smaller volume than a liter, the concentration number looks different even though the amount of substance is proportional.
Many European labs prefer using mg/L or standardizing to molar units. You can learn more about those variations in our general medical unit conversion calculator.
How to Convert mg/L to mg/dL (Formula & Examples)
The math required to convert these units is very simple. Since there are 10 deciliters in 1 liter, the factor is always 10.
To convert milligrams per liter to milligrams per deciliter, you divide the value by 10.
The Formula:
mg/L ÷ 10 = mg/dL
Calculation Example: Let’s say you have a C-Reactive Protein (CRP) test result of 50 mg/L.
To find the mg/dL value, you divide 50 by 10.
50 ÷ 10 = 5
The result is 5.0 mg/dL.
How to Convert mg/dL to mg/L
Sometimes you may need to convert the other way around. If your lab report is in mg/dL but your reference chart uses mg/L, you will need to adjust the number.
To convert from mg/dL to mg/L, you multiply the value by 10.
The Formula:
mg/dL × 10 = mg/L
Calculation Example: Let’s say you have a Glucose result of 90 mg/dL.
To find the mg/L value, you multiply 90 by 10.
90 × 10 = 900
The result is 900 mg/L.
If you perform this calculation frequently, you can save time by using our dedicated mg/dL to mg/L calculator.

Why Medical Unit Conversion Matters
Medical unit conversion is vital for patient safety and accurate diagnosis. Different countries and different laboratories use varying standards for reporting data.
In the United States, mg/dL is the standard for many blood tests like glucose and cholesterol. However, other regions may report these same tests in mmol/L.
If you are comparing results from different labs, you must ensure the units match. For example, confusing a glucose reading in mmol/L with mg/dL could lead to dangerous medical errors.
For accurate glucose conversions specifically, you can use our mmol/L to mg/dL tool.
Common Substances Measured in mg/L and mg/dL
Several key health markers are measured using these units. Knowing which unit is standard for your test helps in tracking your health trends.
C-Reactive Protein (CRP)
CRP is a marker of inflammation. It is very commonly reported in mg/L, especially for high-sensitivity cardiac tests.
Bilirubin
Bilirubin levels indicate liver health. While typically reported in mg/dL in the US, international research often lists it in mg/L or µmol/L.
Albumin
This protein is essential for maintaining blood volume. Conversions for albumin are frequent when comparing hospital records from different networks.
Frequently Asked Questions (FAQ)
Is mg/L the same as ppm?
Yes, for dilute aqueous solutions like water or blood plasma, 1 mg/L is approximately equivalent to 1 part per million (ppm). This is because 1 liter of water weighs approximately 1000 grams or 1,000,000 milligrams.
Why do some labs use mg/L and others mg/dL?
It often depends on regional standards and the specific instrument used. The US healthcare system favors mg/dL for metabolites, while scientific literature and European systems often prefer liter-based measurements.
How do I convert mg/L to percentages?
To convert mg/L to a percentage, you divide the mg/L value by 10,000. For example, 1000 mg/L is equal to 0.1%.
Conclusion
Accurately interpreting your lab results is the first step toward managing your health. Whether you are a student, a researcher, or a patient, knowing how to convert mg/l to mg/dl ensures you understand the data correctly.
Use the calculator above for instant results anytime you review your blood work. If you need to convert other units, explore our full suite of tools, including the mg/dL to mg/L converter for reverse calculations.
