ng/dl to nmol/L Calculator

Formula

The formula to convert ng/dl to nmol/L is:

\[ C (\text{nmol/L}) = \left( \frac{C (\text{ng/dl})}{MW (\text{g/mol})} \right) \times 10 \]

Where:

C (nmol/L) – The concentration in nanomoles per liter.
C (ng/dl) – The concentration in nanograms per deciliter.
MW (g/mol) – The molecular weight of the substance in grams per mole.

Definition

Concentration (C): The amount of a substance in a given volume.
Molecular Weight (MW): The mass of one mole of a substance, measured in grams per mole.

Example

Let's say the concentration (C) is 50 ng/dl and the molecular weight (MW) is 300 g/mol. Using the formula:

\[ C (\text{nmol/L}) = \left( \frac{50}{300} \right) \times 10 = 1.67 \text{ nmol/L} \]

So, the concentration is approximately 1.67 nmol/L.

Significance

Converting ng/dl to nmol/L is important in the medical field, particularly in endocrinology, where hormone levels are measured. Since different substances have different molecular weights, this conversion allows for a standardized comparison of concentration levels across various substances.
