nmol/L to ng/dL Conversion Formula
The following formula is used to convert a concentration from nmol/L to ng/dL:
Variables:
- C(ng/dL) is the concentration in nanograms per deciliter
- C(nmol/L) is the concentration in nanomoles per liter
- MW(g/mol) is the molar mass of the specified chemical form in grams per mole
To convert the concentration from nmol/L to ng/dL, multiply the concentration in nmol/L by the molecular weight in g/mol and then divide by 10.
| nmol/L | ng/dL |
|---|---|
| 0.1 | 2.884 |
| 0.2 | 5.768 |
| 0.3 | 8.653 |
| 0.5 | 14.421 |
| 1 | 28.842 |
| 2 | 57.684 |
| 2.5 | 72.105 |
| 3 | 86.526 |
| 4 | 115.368 |
| 5 | 144.210 |
| 7.5 | 216.315 |
| 10 | 288.420 |
| 12 | 346.104 |
| 15 | 432.630 |
| 20 | 576.840 |
| 25 | 721.050 |
| 30 | 865.260 |
| 35 | 1009.470 |
| 40 | 1153.680 |
| 50 | 1442.100 |
| * Rounded to 3 decimals. Formula: ng/dL = nmol/L × (MW/10). Example assumes Testosterone (MW 288.42 g/mol): 1 nmol/L ≈ 28.842 ng/dL. | |
What is Concentration Conversion?
Concentration conversion is the process of converting the concentration of a substance from one unit of measurement to another. This is often necessary when comparing results from different tests or when following specific guidelines that require a certain unit of measurement. The conversion uses molar mass, the mass per mole of the specified chemical entity. Match the analyte and chemical form; converting units does not make different assays or total and free hormone results interchangeable.
How to Convert nmol/L to ng/dL?
The following steps outline how to convert the concentration from nmol/L to ng/dL:
- First, determine the concentration in nmol/L.
- Next, determine the molecular weight of the substance in g/mol.
- Use the conversion formula: C(ng/dL) = (C(nmol/L) * MW(g/mol)) / 10.
- Finally, calculate the concentration in ng/dL.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Concentration (C(nmol/L)) = 50 nmol/L
Molar mass (MW(g/mol)) = 300 g/mol. The converted concentration is 50 × 300 ÷ 10 = 1,500 ng/dL.
