Enter a value in micrograms per deciliter (mcg/dL) into the calculator to convert it to nanograms per milliliter (ng/mL). You can also choose an analyte for context, although the conversion factor remains the same: 1 mcg/dL = 10 ng/mL.

mcg/dL to ng/mL Formula
The following formula is used to convert micrograms per deciliter (mcg/dL) into nanograms per milliliter (ng/mL).
ng/mL = mcg/dL \times 10
Variables:
- ng/mL is the concentration in nanograms per milliliter
- mcg/dL is the concentration in micrograms per deciliter
- 10 is the conversion factor between the two units
To convert mcg/dL to ng/mL, multiply the value in mcg/dL by 10. This works because 1 mcg equals 1000 ng and 1 dL equals 100 mL, giving a net factor of 10.
What is mcg/dL to ng/mL Conversion?
The units mcg/dL and ng/mL both describe concentration, but they use different mass and volume scales. A lab result in mcg/dL can be converted directly into ng/mL using a fixed relationship. Since 1 mcg/dL equals 10 ng/mL, it is easy to compare lab values across reports, references, or testing systems that use different units.
This type of conversion is commonly encountered with blood and serum tests such as vitamin D, ferritin, testosterone, estradiol, cortisol, and thyroxine measurements. Although the analyte may differ, the unit conversion itself remains the same.
How to Convert mcg/dL to ng/mL?
The following steps outline how to convert mcg/dL to ng/mL.
- First, determine the concentration in mcg/dL.
- Next, use the conversion factor 10.
- Multiply the mcg/dL value by 10 to find the equivalent concentration in ng/mL.
- Finally, verify your answer using the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Value in mcg/dL = 7.5
Conversion factor = 10
ng/mL = 7.5 × 10 = 75
mcg/dL to ng/mL Conversion Table
The table below shows several common mcg/dL values and their equivalents in ng/mL using the rule ng/mL = mcg/dL × 10.
| Value (mcg/dL) | Conversion Factor | Result (ng/mL) |
|---|---|---|
| 1 | × 10 | 10 |
| 2.5 | × 10 | 25 |
| 5 | × 10 | 50 |
| 7.5 | × 10 | 75 |
| 10 | × 10 | 100 |
| 12.3 | × 10 | 123 |
| 20 | × 10 | 200 |
Many laboratory references and reports may use either mcg/dL or ng/mL. Because the conversion factor is fixed, switching between the two is straightforward. Multiply by 10 to convert mcg/dL to ng/mL, and divide by 10 to convert ng/mL back to mcg/dL.
