1. What is nM to ng/mL Conversion?

The nM to ng/mL conversion is used to convert concentration measurements from nanomolar (nM) to nanograms per milliliter (ng/mL). This conversion requires knowing the molecular weight of the substance being measured.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( nM \) — Concentration in nanomolar
• \( MW \) — Molecular weight in grams per mole (g/mol)
• \( 1000 \) — Conversion factor

Explanation: The equation accounts for the relationship between molar concentration and mass concentration, converting between number of molecules and mass of substance.

3. Importance of Unit Conversion

Details: Accurate unit conversion is crucial for comparing measurements across different studies, preparing solutions, and interpreting laboratory results.

4. Using the Calculator

Tips: Enter the concentration in nM and the molecular weight in g/mol. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why do we need molecular weight for this conversion?
A: Molecular weight is needed because nM measures number of molecules while ng/mL measures mass. The MW connects these two measurements.

Q2: What if I don't know the molecular weight?
A: You must know the molecular weight of your specific compound to perform this conversion accurately.

Q3: Can this be used for any substance?
A: Yes, as long as you know the correct molecular weight of the substance you're measuring.

Q4: What's the difference between nM and ng/mL?
A: nM (nanomolar) measures molar concentration (molecules per volume), while ng/mL measures mass concentration (mass per volume).

Q5: How precise is this conversion?
A: The conversion is mathematically exact, but the precision depends on the accuracy of your nM measurement and molecular weight value.
