Enter the concentration in mg/dL into the calculator to convert it to ng/mL. The analyte or test selection is optional and only labels the result.

mg/dL to ng/mL Converter

Enter a value in mg/dL to convert it to ng/mL

Conversion formula: ng/mL = mg/dL × 10,000

mg/dL to ng/mL Formula

The following formula is used to convert a concentration from milligrams per deciliter to nanograms per milliliter.

ng/mL = mg/dL × 10,000

The reverse conversion can also be written as:

mg/dL = ng/mL ÷ 10,000

Variables:

  • ng/mL is the concentration in nanograms per milliliter
  • mg/dL is the concentration in milligrams per deciliter
  • 10,000 is the conversion factor between the two units

To convert mg/dL to ng/mL, multiply the value in mg/dL by 10,000.

What is mg/dL to ng/mL Conversion?

mg/dL and ng/mL are both units of concentration that express mass per volume. The difference is only in the scale of the units being used. A milligram is much larger than a nanogram, and a deciliter is larger than a milliliter, so converting between the two creates a constant multiplier.

This relationship comes from the metric definitions:

  • 1 mg = 1,000,000 ng
  • 1 dL = 100 mL
  • Therefore, 1 mg/dL = 10,000 ng/mL

Because this is a unit conversion rather than a substance-specific formula, the same factor works for glucose, cholesterol, triglycerides, creatinine, bilirubin, uric acid, lactate, and any other analyte reported in these units.

How to Calculate mg/dL to ng/mL?

The following steps outline how to convert mg/dL to ng/mL.


  1. First, determine the concentration in mg/dL.
  2. Next, use the conversion factor of 10,000.
  3. Multiply the mg/dL value by 10,000 to find the equivalent concentration in ng/mL.
  4. After calculating the result, verify your answer with the calculator above.

mg/dL to ng/mL Conversion Table

The table below lists example conversions using the relationship ng/mL = mg/dL × 10,000.

Analyte / Test Example Value (mg/dL) Equivalent in ng/mL
Glucose 90 900,000 ng/mL
Total Cholesterol 200 2,000,000 ng/mL
Triglycerides 150 1,500,000 ng/mL
Creatinine 1.0 10,000 ng/mL
Total Bilirubin 1.2 12,000 ng/mL
Uric Acid 7.0 70,000 ng/mL
Lactate 2.0 20,000 ng/mL

In routine lab reporting, many values are presented in mg/dL, while some research or reference materials use ng/mL. Knowing the factor of 10,000 makes it easy to compare measurements across sources.

Example Problem

Use the following variables as an example problem to test your knowledge.

Concentration = 1.2 mg/dL

Using the formula:

ng/mL = 1.2 × 10,000 = 12,000

The final answer is 12,000 ng/mL.
