  • Water238.1 mL by volume

Add 11.9 mL Product and 238.1 mL Water to make 250 mL.

How to mix 1:20 in 250 mL

This calculator preloads a 1:20 dilution for a total batch of 250 mL. Confirm the total volume, then follow the component amounts surfaced above. Optional gram targets are derived from these volumes after you enter the exact product densities.

  1. Confirm 1:20 product:water by volume and the exact product instructions.
  2. Measure the displayed amounts: 11.9 mL Product, 238.1 mL Water.
  3. Combine only the named components in the order required by the product instructions. Do not add unlisted liquid.

Accuracy tips

Need to batch multiple containers? Duplicate this preset, change the container size, and use the copyable mix line for fast relabelling. Only use gram targets after entering densities from the exact product data.

How this is calculated

For a ratio of a:b, each part is a/(a+b) and b/(a+b) of the total. PPM mode uses 1 ppm ≈ 1 mg/L for aqueous solutions. Show gram targets to convert those calculated volumes using the densities you provide; the ratio itself remains volume-based.
