Dilution Calculator (Cleaners & Disinfectants)

Just enter the concentrate concentration, the target concentration (% or ppm), and how much you want to make to instantly get the amount of concentrate needed and the water to add. You can also specify by dilution ratio, making it easy to mix cleaners, disinfectants, and sodium hypochlorite solutions.

Example: to dilute 6% chlorine bleach (sodium hypochlorite) to 200 ppm (0.02%) and make 1 L, you need about 3.3 mL of concentrate and about 996.7 mL of water. When actually using it, follow the product label and guidance from official authorities, and take safety precautions such as ventilation and gloves.

How it works

  • In "By target concentration" mode, the concentrate needed = total amount x target concentration / concentrate concentration, and the water to add = total amount - concentrate.
  • The target concentration can be entered as either % or ppm, automatically converted as 1% = 10,000 ppm. Specifying low concentrations in ppm is easier to read.
  • In "By dilution ratio" mode, the concentrate = total amount / dilution ratio. For example, a 100x dilution with a 1 L total works out to about 10 mL of concentrate plus 990 mL of water.
  • The total amount can be switched between mL and L, and the concentrate and water amounts are shown in an easy-to-read unit based on the quantity.
  • If the target concentration exceeds the concentrate concentration, it cannot be diluted, so the tool prompts you to review your input.
  • When handling chlorine bleach and similar products, always follow the product label and guidance from official authorities, and take safety precautions such as ventilation and wearing gloves.
