Why do we use litres to measure the capacity of an oven? Does it mean it can hold x litres of water in it?

Question

Was thinking to buy an OTG and it’s coming in different sizes ranging from 25 – 50 litres. What does the litre here really indicate?

Answer 1

A liter is a unit of volume. It’s the same as a cubic decimeter or a a cube 10cm on each side. It’s also the volume of water that has a mass of 1kg.
