Dilution Ratio Calculator
Calculate concentrate and water amounts for any dilution ratio using C1V1 = C2V2. Works for cleaning products, syrups, and lab solutions.

What is it?
The dilution formula C1V1 = C2V2 states that the amount of solute stays constant before and after dilution. For a simple ratio (e.g. 1:10), concentrate percentage = 1/10 = 10%. To make 1,000 mL of 1:10 solution: 100 mL concentrate + 900 mL water. This applies to cleaning products, cocktail syrups, stock solutions, and food-grade concentrates.
How to use
Enter the concentrate ratio parts (usually 1), the total ratio parts (e.g. 10 for 1:10), and how much finished solution you need in mL. The calculator outputs exactly how much concentrate and water to measure.
Example scenario
1:32 all-purpose cleaner (1 part concentrate, 32 total parts): to make 1L of ready-to-use spray, mix 31.25 mL concentrate with 968.75 mL water. The concentrate is 3.125% of the final solution.
Pro tip
Common dilution ratios: all-purpose cleaner 1:32, heavy-duty degreaser 1:8, coffee syrup 1:4 (with water), stock concentrate 1:6. Always add concentrate TO water, not water to concentrate — this prevents splashing with caustic solutions and ensures proper mixing. Label your diluted solutions with the date and ratio.
