Capacity is the total in litres as listed. Power use is compared only when it was measured at 32 °C outside, and the inside setting is shown beside it; a dual-zone figure (fridge and freezer both running) is never set against a single-zone one. Most figures come from the retailers' product pages, because the brands don't allow their own pages to be reused.
