OK - here's today's poser!
Reading the 'back to how we were' thread reminded me of this :-Litres are liquid measures - Yes?
Kilo's are dry measures - Yes?
Why then are the sacks of Cat Litter I have just bought labelled 30 litres?
Why are sacks of potting compost labelled in litres?
How can a litre be used as both a liquid and a dry measure?
It is not logical - not to me anyway!

It has something to do with the bowls/tub that is being used. Many bowls tubs both large and small can not only be used for dry measures but also liquids. The problem is dry measures can be different in weight therefore it is difficult for the manufacturer to put a price on the bowl/tub based on weight. For example, if someone bought a tub with the intention of filling it with coco pops cereal, it is going to weight differently to that of someone wanting to put their rock collection in it.This is where litres comes in. Because a plastic or glass tub/bowl can be used for liquids, it does not matter what the liquid weighs, the volume of the liquid will always be the same. Hence why bowls/tubs that can be used for liquids as well as dry measures will have it's dimensions calculated to find out what is the safe level of 'volume' the bowl/tub can take.
This is why you will find cat litter boxes are always marked as 'volume' and the same is with garden's. You cannot weigh a garden but you can measure the 'volume' the garden takes up just by using mathematics Height x Length x Width (Depth). Once you have those dimensions you can work out the volume and thus know how many litres of potting compost to use. Same principle applies to litter boxes.
