Capacity figures in litres can mislead if you do not know which one you are reading. Gross volume measures the whole space enclosed by the inner walls and door. Net or storage volume subtracts the space taken by the evaporator cover, fans, shelves, ducts, and the gap that must be left for air to circulate. Net volume is always lower, sometimes considerably.
When comparing two units, make sure both quote the same measure. A cabinet advertised at a higher gross figure might hold less usable stock than a competitor quoting net. Beyond litres, check how the space is shaped: shelf spacing, whether GN pans or crates fit, and how much is lost to door racks or awkward corners. For display units, the display area or shelf length is often more useful than volume.
A dairy retailer in Jaipur choosing between two glass-door coolers might find one quotes gross and the other net. By counting how many 1-litre milk packets each shelf actually holds, the shop gets a far more useful comparison than the brochure figures.
