Ng to nM Conversion Formula:
| From: | To: |
The ng to nM conversion formula calculates nanomolar concentration from nanograms, molecular weight, and volume. This conversion is essential in biochemistry and molecular biology for standardizing concentration measurements across different units.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts mass (ng) to molar concentration (nM) by accounting for the molecular weight of the substance and the volume of the solution.
Details: Accurate concentration conversion is crucial for experimental reproducibility, proper reagent preparation, and comparing results across different studies and laboratories.
Tips: Enter nanograms (ng), molecular weight in g/mol, and volume in liters. All values must be positive numbers greater than zero.
Q1: Why convert ng to nM?
A: Converting mass to molar concentration allows for standardized comparisons between different compounds and experiments, as molar concentration accounts for molecular weight differences.
Q2: What is the significance of molecular weight in this conversion?
A: Molecular weight determines how many molecules are present in a given mass, which is essential for converting mass concentration to molar concentration.
Q3: Can this calculator handle different volume units?
A: The calculator requires volume in liters. Convert other volume units to liters before calculation (1 mL = 0.001 L, 1 μL = 0.000001 L).
Q4: What are typical molecular weight ranges?
A: Molecular weights vary widely: small molecules (100-500 g/mol), proteins (10,000-100,000 g/mol), nucleic acids (thousands to millions g/mol).
Q5: How accurate is this conversion?
A: The conversion is mathematically precise. Accuracy depends on the precision of your input values (ng measurement, molecular weight, and volume).
