Conversion Formula:
Where:
nmol = nanomoles
mg = milligrams
MW = molecular weight (g/mol)
From: | To: |
The conversion between milligrams (mg) and nanomoles (nmol) is essential in chemistry and biochemistry when working with substances where the number of molecules is more relevant than their mass. This conversion requires knowledge of the substance's molecular weight.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts mass (mg) to amount of substance (nmol) using the substance's molecular weight as a conversion factor.
Details: Accurate unit conversion is crucial for preparing solutions with specific molar concentrations, comparing substance quantities, and performing stoichiometric calculations in chemical and biological experiments.
Tips: Enter the mass in milligrams and the molecular weight in g/mol. Both values must be positive numbers. The result will be in nanomoles.
Q1: Why convert between mg and nmol?
A: Many biological experiments require specific molar amounts rather than mass amounts, making this conversion essential for accurate preparation of solutions.
Q2: Where can I find molecular weights?
A: Molecular weights can be found in chemical databases, product specifications, or calculated from chemical formulas using atomic weights.
Q3: What's the difference between nmol and pmol?
A: 1 nmol = 1000 pmol. Nanomoles (10⁻⁹ moles) are 1000 times larger than picomoles (10⁻¹² moles).
Q4: Can I use this for proteins?
A: Yes, but remember to use the protein's molecular weight (including any tags or modifications if relevant).
Q5: How precise should my molecular weight be?
A: For most applications, 2-4 decimal places are sufficient, but highly precise work may require more accurate MW values.
