Question

Why refrigerator capacity is measured in litres?

Answer 1

It’s a commonly used measure of volume, and a closer fit than for example cubic meters which would make the fridge look small because it would almost always be less than 1 cubic meter. 

In areas where the metric system isn’t used I do see fridges advertised in cubic feet.

So in short, they use whatever measurement they think their customers will recognize and understand.
