Formula
V2 = C1 × V1 ÷ C2. Diluent = V2 − V1.
A 10 percent solution and a 2 percent target is a 5 to 1 concentration ratio. The volume grows by that factor. Units stay whatever you typed, as long as each pair matches.

Dilution calculator for C1V1 = C2V2
This dilution calculator finds the final volume when you dilute a starting concentration to a weaker one. Use the same equation as a bleach dilution calculator, a chemical dilution calculator, or a soft wash mix calculator. You enter both concentrations. The page does not prescribe a mix.

Dilution arithmetic only. Follow the product label. Do not mix products the label says are incompatible. This is not a treatment or application rate.
How it works
The amount of solute does not change.
C1 times V1 equals C2 times V2. C1 and C2 must use the same concentration unit, such as percent. V1 and V2 use the same volume unit, such as milliliters or gallons. Final volume is C1 times V1 divided by C2. Diluent to add is the final volume minus the starting volume. If the target is stronger than the start, the equation would be concentrating, not diluting, and the form stops. Follow the product label. Do not combine products the label says are incompatible. This is arithmetic, not an application rate for a surface, a crop, or a person.

Example
100 units of a 10 percent solution down to 2 percent.
Final volume is 500.00. Diluent to add is 400.00. Those units might be milliliters or gallons. The ratio is 5.00 to 1. A bleach dilution calculator uses this only after you type the percent on the bottle and the percent the label tells you to reach.

Tips
Read the label before you scale a soft wash.
A soft wash mix calculator on this page will not invent a bleach strength. Enter the starting percent and the target percent from the product instructions. If the label gives a mix by parts instead of percent, convert the parts to a concentration first or do not use this form.

Equipment
The sprayer is the equipment. The mix is not.
Cleaning businesses sometimes finance wash equipment. Dengaro takes equipment applications from $15,000 to $2 million. The dilution result is not a chemical order and not a treatment plan.
Important questions
Know what to expect.
Can this chemical dilution calculator solve for a stronger mix?+
No. If the target concentration is higher than the starting concentration, the message asks you to stop. Adding diluent cannot make a solution stronger.
What units does the bleach dilution calculator expect?+
Any matching pair. Percent with percent, and one volume unit throughout. It does not convert ounces to liters. It does not tell you a safe bleach strength.
Why is the concentration ratio not the same as parts of water?+
The ratio shown is starting concentration divided by target concentration. Diluent volume is final volume minus what you started with. Read both lines before you measure.
Does the calculator name a product?+
No. A soft wash mix calculator here is the same equation with your numbers. Product choice and compatibility stay on the label.
