Converting concentrations from micrograms per deciliter (µg/dL) to millimoles per liter (mmol/L) is a common task in medical and laboratory settings. This conversion is essential for comparing concentration values in different units, particularly when dealing with substances with known molecular weights.

## Formula

To convert a concentration from µg/dL to mmol/L, use the following formula:

C(mmol/L)=C(µg/dL)MW(g/mol)×10C(mmol/L) = \frac{C(µg/dL)}{MW(g/mol)} \times 10C(mmol/L)=MW(g/mol)C(µg/dL)×10

where:

- C(mmol/L)C(mmol/L)C(mmol/L) is the concentration in millimoles per liter.
- C(µg/dL)C(µg/dL)C(µg/dL) is the concentration in micrograms per deciliter.
- MW(g/mol)MW(g/mol)MW(g/mol) is the molecular weight of the substance in grams per mole.

## How to Use

To use the Ug/Dl to Mmol/L Calculator:

- Enter the concentration in micrograms per deciliter (µg/dL).
- Enter the molecular weight of the substance in grams per mole (g/mol).
- Click the “Calculate” button.
- The concentration in millimoles per liter (mmol/L) will be displayed.

## Example

Suppose you have a substance with a concentration of 50 µg/dL and a molecular weight of 180 g/mol. Using the calculator:

- Enter 50 in the concentration field.
- Enter 180 in the molecular weight field.
- Click “Calculate.”
- The concentration is calculated as 0.278 mmol/L.
