Dilution Calculator for Mixing Ratios

Calculate concentrate and water for final-solution ratios or product-to-water ratios using metric or US customary volume units.

Start here

Read the product label and choose final-solution ratio or product-to-water ratio.

Useful for

Mix cleaning concentrate according to a product label

Choose this only when the label says one part product to N parts water. A 1:10 mix has 11 total parts.

Concentrate0.091 US gal344.1 mL
Water0.909 US gal3.441 L
Product concentration9.09%11 total parts

The calculator handles ratio arithmetic only. Confirm the label's exact wording, permitted use, container, and measuring precision.

Follow the product label, safety data sheet, protective equipment, ventilation, and mixing order. Never combine chemicals unless the manufacturer explicitly permits it.

Not for medication, injections, laboratory standards, or other high-risk precision dilution.

Quick answer

Calculate concentrate and water for a mixing ratio

Choose whether 1:N means one part concentrate in N total parts or one part concentrate plus N parts water, then enter the required final or water volume.

Use this when

A cleaner, garden product, laboratory-style solution, or other concentrate gives a ratio and you need measurable liquid amounts.

Know the boundary

A ratio calculator cannot confirm chemical compatibility, concentration limits, protective equipment, or safe mixing order; always follow the product label or procedure.

About this tool

Calculate concentrate and water for final-solution ratios or product-to-water ratios using metric or US customary volume units.

Your ratio and volume inputs are calculated locally in your browser and are not uploaded to a server.

Reminder

Always follow the product label, safety data sheet, required protective equipment, compatibility rules, and mixing order. Never mix chemicals unless the manufacturer explicitly says it is safe. This calculator does not determine whether a mixture is safe or effective.

How to use it

  1. Read the product label and choose final-solution ratio or product-to-water ratio.
  2. Enter the ratio and desired final volume in your preferred unit.
  3. Calculate the concentrate and water amounts, then follow the product's mixing and safety instructions.

Common use cases

  • Mix cleaning concentrate according to a product label
  • Scale a garden or workshop solution
  • Convert a ratio to a smaller spray bottle
  • Distinguish one-part product in final solution from one-part product plus N parts water

Two Common Meanings of 1:N

Labels do not always use ratio notation the same way. One part product in N total parts is different from one part product plus N parts water. Choose the mode that matches the label's written instructions.

Safe Mixing Checklist

The arithmetic cannot tell whether a product is compatible with a container, surface, crop, animal, or another chemical. The product label and safety data sheet remain the controlling instructions.

  • Confirm whether the label defines a final concentration or a product-to-water ratio.
  • Use measuring equipment appropriate for the required precision.
  • Follow ventilation, protective equipment, temperature, storage, and mixing-order instructions.
  • Do not use this general-purpose tool for medication, injections, laboratory standards, or other high-risk precision work.

FAQ

What is the difference between 1:10 final solution and 1:10 product to water?

For one part product in ten total parts, product is 10% of the final volume. For one part product plus ten parts water, the mixture has eleven total parts.

Can I calculate ounces or gallons?

Yes. Choose US fluid ounces, quarts, or gallons. Metric milliliters and liters are also available.

Should I add water or concentrate first?

Follow the product label or safety data sheet. The safe mixing order depends on the specific substance and container.

Can I use this for medication or laboratory work?

No. Medical, pharmaceutical, and precision laboratory dilution requires validated concentrations, procedures, and qualified oversight.
