nM to ng/mL Conversion Equation:
From: | To: |
The nM to ng/mL conversion is used to convert concentration measurements between molarity (nM, nanomolar) and mass concentration (ng/mL, nanograms per milliliter). This is essential in biochemistry and pharmacology when comparing measurements made with different techniques.
The calculator uses the conversion equation:
Where:
Explanation: The equation converts the molar concentration to mass concentration by accounting for the molecular weight of the substance and appropriate unit conversions.
Details: Accurate unit conversion is crucial for comparing experimental results, preparing solutions with precise concentrations, and interpreting biochemical data across different measurement techniques.
Tips: Enter the concentration in nM and the molecular weight in g/mol. Both values must be positive numbers. The result will be displayed in ng/mL.
Q1: Why is molecular weight needed for this conversion?
A: Molecular weight connects the molar quantity (nM) to mass (ng), as different molecules have different masses even at the same molar concentration.
Q2: How precise should the molecular weight be?
A: Use the exact molecular weight for maximum accuracy, especially for small molecules. For proteins, use the average molecular weight based on amino acid sequence.
Q3: Can this be used for any substance?
A: Yes, as long as you know the molecular weight. Works for small molecules, proteins, nucleic acids, etc.
Q4: What's the difference between nM and ng/mL?
A: nM measures the number of molecules per volume, while ng/mL measures the mass of molecules per volume. The conversion depends on the molecule's size.
Q5: How do I convert back from ng/mL to nM?
A: Use the inverse equation: nM = (ng/mL × 1000) / MW
