pg/mL to ng/dL Formula
The following formula is used to convert picograms per milliliter to nanograms per deciliter.
ng/dL = pg/mL / 10
Variables:
- ng/dL is the concentration in nanograms per deciliter
- pg/mL is the concentration in picograms per milliliter
To calculate the value in ng/dL, divide the concentration in pg/mL by 10.
What is pg/mL to ng/dL?
pg/mL and ng/dL are both units used to describe very small mass concentrations, often in hormone and laboratory test results. The conversion is based only on the units themselves, not on the substance being measured. Since 1 nanogram equals 1000 picograms and 1 deciliter equals 100 milliliters, 1 pg/mL is equal to 0.1 ng/dL. This means converting from pg/mL to ng/dL is always done by dividing by 10.
How to Convert pg/mL to ng/dL?
The following steps outline how to convert pg/mL to ng/dL.
- First, determine the concentration in pg/mL.
- Next, use the conversion relationship ng/dL = pg/mL / 10.
- Finally, divide the pg/mL value by 10 to find the equivalent concentration in ng/dL.
- After inserting the value and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following value as an example problem to test your knowledge.
Value = 100 pg/mL
ng/dL = 100 / 10 = 10 ng/dL
pg/mL to ng/dL Conversion Table
The table below shows example conversions using the relationship ng/dL = pg/mL / 10.
| Value (pg/mL) | Value (ng/dL) |
|---|---|
| 10 | 1 |
| 25 | 2.5 |
| 50 | 5 |
| 75 | 7.5 |
| 100 | 10 |
| 150 | 15 |
In practice, lab reports may display results in either pg/mL or ng/dL depending on the test and reporting standard. Knowing that the conversion is a simple factor of 10 makes it easy to compare values across different references and calculators.
