Calculation method
Calculation method
Working solution per pack (L)
Concentrate mL × (1 + water parts) / 1000.
Cost per working litre ($/L)
Pack price / working litres per pack.
Concentrate needed (mL)
Target working volume / (1 + water parts).
Water needed (mL)
Target working volume − concentrate needed.
Whole packs to purchase
Round up concentrate needed / concentrate volume per pack.

Assumptions & limits
Assumptions & limits
- Copy the manufacturer’s volumetric label ratio: 1 part concentrate plus the entered water parts. It is not a chemical-concentration conversion or a recommendation to dilute any product. Do not mix products; confirm that the label permits the use.
