Frequently Asked Questions

What is the dilution equation used for?

The dilution equation (M1V1 = M2V2) is used to calculate how to dilute a solution to achieve a desired concentration, or to verify that a dilution was performed correctly.

Can I use negative values?

No, all values must be positive since they represent physical quantities that cannot be negative.

What if I enter all 4 values?

If you enter all 4 values, the calculator will verify if they satisfy the equation M1V1 = M2V2. If they do, it will show "Equation satisfied". If not, it will show an error.

How accurate are the unit conversions?

All conversions use standard conversion factors with high precision. Results are displayed to 6 decimal places for accuracy.

Is my data secure?
