Numpty question when comparing bedding!

[ellis9905]

I apologise now for the stupid question!!

I'm comparing various different bedding options and prices... Now some bags are in litres and others kg!!

So which is bigger... 20kg or 75litres???

Buffet nibbles for anyone answering!

I know for water that 1 litre equals 1kg...
