1. What is μg/mL to nmol/L Conversion?

This calculator converts concentration values from micrograms per milliliter (μg/mL) to nanomoles per liter (nmol/L) with percentage adjustment. This conversion is essential in biochemistry and pharmacology where molecular concentrations need to be compared.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \mu g/mL \) — Concentration in micrograms per milliliter
• \( MW \) — Molecular weight in grams per mole
• \( 1000 \) — Conversion factor (1000 nmol = 1 μmol)
• \( \text{percentage adjustment} \) — Percentage purity or recovery (as decimal)

Explanation: The equation first converts mass concentration to molar concentration, then adjusts for percentage purity or recovery.

3. Importance of Molecular Weight

Details: Molecular weight is crucial for accurate conversion as it relates the mass of a substance to its molar quantity. The percentage adjustment accounts for purity or recovery in experimental procedures.

4. Using the Calculator

Tips: Enter concentration in μg/mL, molecular weight in g/mol, and percentage adjustment (default is 100%). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why convert μg/mL to nmol/L?
A: Molar units (nmol/L) allow comparison between different compounds based on number of molecules rather than mass.

Q2: Where can I find molecular weight?
A: Molecular weights are available in chemical databases, product specifications, or can be calculated from chemical formulas.

Q3: What is percentage adjustment for?
A: It accounts for purity of a compound or recovery rate in an extraction process (e.g., 95% purity would use 0.95).

Q4: When would I use 100% adjustment?
A: When working with pure compounds or when you want the theoretical conversion without purity/recovery considerations.

Q5: Can this be used for any compound?
A: Yes, as long as you know the molecular weight and appropriate percentage adjustment.
