How to mix 30% coolant / 70% water in 750 mL

This calculator preloads a 30% coolant / 70% water dilution for a total batch of 750 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 30:70 coolant:water by volume and the exact product instructions.
  2. Measure the displayed amounts: 225 mL Coolant, 525 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.
