1. What is mM to mg/mL Conversion?

The millimolar (mM) to milligrams per milliliter (mg/mL) conversion is used to convert between molar concentration and mass concentration units in chemistry and biochemistry. This is particularly useful when preparing solutions or comparing concentrations across different measurement systems.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{mM} \) — Millimolar concentration (mmol/L)
• \( \text{MW} \) — Molecular weight (g/mol)
• \( 1000 \) — Conversion factor (1000 mg/g and 1000 mL/L cancel out)

Explanation: The equation converts the number of millimoles per liter to milligrams per milliliter by accounting for the molecular weight of the substance.

3. Importance of Concentration Conversion

Details: Accurate concentration conversion is essential for solution preparation, experimental protocols, and comparing results across studies that may use different concentration units.

4. Using the Calculator

Tips: Enter the millimolar concentration and molecular weight. Both values must be positive numbers. The molecular weight should be in g/mol (the standard unit).

5. Frequently Asked Questions (FAQ)

Q1: Why do I need to know the molecular weight?
A: The molecular weight is needed to convert between molar units (which count molecules) and mass units (which measure weight).

Q2: Can I use this for any chemical compound?
A: Yes, as long as you know the correct molecular weight of the compound.

Q3: How do I find the molecular weight of my compound?
A: You can calculate it by summing atomic weights of all atoms in the molecule, or look it up in chemical databases or the compound's documentation.

Q4: What's the difference between mM and mg/mL?
A: mM measures molar concentration (number of molecules per volume), while mg/mL measures mass concentration (weight of substance per volume).

Q5: Can I convert mg/mL back to mM?
A: Yes, the reverse calculation is: mM = (mg/mL × 1000) / MW
