Frequently Asked Questions

What is the dilution formula? +

The dilution formula is C₁V₁ = C₂V₂, where C₁ is initial concentration, V₁ is initial volume, C₂ is final concentration, and V₂ is final volume. This formula ensures that the amount of solute remains constant during dilution.

How do I calculate serial dilutions? +

Use the Serial Dilution mode. Enter your initial concentration, dilution factor per step (e.g., 10 for 1:10 dilution), and number of steps. The calculator will show concentrations at each step and total dilution factor.

How do I convert between US and Metric units? +

Click the unit toggle buttons at the top (🌍 Metric or 🇸 US Customary). The calculator will automatically convert all volume units. 1 US gallon = 3.785 liters, 1 fl oz = 29.57 mL.

How accurate is this calculator? +

Our calculator uses precise mathematical formulas and standard conversion factors. However, always verify critical calculations and consider temperature effects, solution density, and measurement precision in real-world applications.

Can I use this for hazardous chemicals? +

Yes, but always consult the Safety Data Sheet (SDS) for the chemical you're using, wear appropriate PPE, and follow all safety protocols. This calculator provides mathematical results only, not safety guidance.
