1. What is mM to % Conversion?

The mM to % conversion calculates weight/volume percentage from millimolar concentration using the molecular weight of the solute. This is commonly used in chemistry and biology to prepare solutions with specific concentrations.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( mM \) — Millimolar concentration
• \( MW \) — Molecular weight (g/mol)
• 10000 — Conversion factor (1000 for mM to M and 100 for %)

Explanation: The formula converts millimoles per liter to grams per 100 mL, which is the definition of percentage concentration (w/v).

3. Importance of Concentration Conversion

Details: Accurate concentration conversion is essential for preparing solutions in laboratories, pharmaceutical formulations, and various chemical processes where precise concentrations are required.

4. Using the Calculator

Tips: Enter the millimolar concentration and molecular weight of your compound. Both values must be positive numbers. The result will be the percentage concentration (weight/volume).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between w/v% and w/w%?
A: w/v% is weight per volume (g/100mL), while w/w% is weight per weight (g/100g). This calculator provides w/v%.

Q2: Can I use this for any solute?
A: Yes, as long as you know its molecular weight. Works for single compounds, not mixtures.

Q3: Why divide by 10000?
A: The factor combines conversion from mM to M (÷1000) and from g/L to % (÷10), plus the percentage definition (per 100).

Q4: How accurate is this conversion?
A: The calculation is mathematically exact, but actual solution preparation accuracy depends on measurement precision.

Q5: What about temperature effects?
A: This assumes standard conditions. For very precise work, temperature effects on density should be considered.
