How to choose a pack size and calculate volume
The volume per pack, number of packs and total volume are different quantities.
Check the unit of measurement
Find the pack size for the specific variant on the product page. Volume in litres, weight in kilograms and the number of units are not interchangeable. If the size or unit is missing, confirm it before ordering.
Calculate whole packs
Divide the required volume by the volume of one pack and round the number of packs up. For example, a 7 l requirement with 5 l packs needs two packs: 10 l in total, with 3 l left over. This is an arithmetic example, not a recommendation for equipment fill volume.
Compare equivalent conditions
The price applies to the selected pack size. Check the number of packs, currency, tax information and delivery before confirming. If no price is shown, request a quote first. The catalogue calculator helps calculate quantities for available pack sizes in litres.
