Dilution Ratio Calculator
Mix cleaning solutions, fertilizers, and chemical concentrates accurately. Convert ratios to real measurements for any container size.
Use the final solution size—spray bottle, mop bucket, etc.
We’ll estimate how many batches you can prepare with your current supply.
Mixing Guide
Concentrate: 3.88 ounces
Water: 124.12 ounces
Total: 128.00 ounces
Batch Planning
Approx. 4.1 full batches with current concentrate.
Notes
Mix 3.88 ounces of concentrate with 124.12 ounces of water to make 128.00 ounces of solution.
Measure concentrate first, then top up with water to the final volume for consistent results.
How to Use This Calculator
Check the label
Locate the manufacturer’s dilution ratio on your concentrate. It’s often written as 1:16, 1:64, etc.
Enter container size
Specify the final amount of solution you want to mix—spray bottle, mop bucket, or reservoir.
Mix according to instructions
Pour the calculated concentrate first, then add water to reach the final volume. Label containers clearly.
Formula
Concentrate Volume = Total Volume × (Part A ÷ (Part A + Part B))
Water Volume = Total Volume − Concentrate Volume
Example: Mix 1:32 in a 1-gallon (128 oz) sprayer → Concentrate = 128 × (1 ÷ 33) ≈ 3.88 oz, Water ≈ 124.1 oz.
Example: 1 quart (32 oz) bottle, ratio 2:5 → Total parts = 7, concentrate ≈ 9.14 oz, water ≈ 22.86 oz.
About the Dilution Ratio Calculator
Improperly mixed solutions waste chemicals or reduce effectiveness. This calculator gives you exact measurements for diluting cleaners, fertilizers, disinfectants, and more.

Frequently Asked Questions
What does 1:32 mean?
For every 1 part concentrate, mix 32 equal parts water. In a 33-part solution, concentrate is about 3% of the total volume.
Should I add water or concentrate first?
Pour concentrate into the container first, then add water up to the final volume. This prevents foam and ensures accurate ratios.
How do I scale recipes?
Multiply both parts of the ratio equally. For example, 1:4 becomes 2:8 or 3:12—each maintains the same dilution strength.
Can I use weight instead of volume?
Only if the concentrate and water have similar density. Otherwise, convert ratios using product-specific mixing charts.
