Aldi growbags - How many ltrs in them?

[peanut]

I've just weighed my Aldi Growbags on the bathroom scales and it weighed about 25lbs. How do I convert it to litres as all the compost bags are sold in ltrs and i'm trying to work out if they are good value or not.

I can't find any conversion sites that show this calculation and am starting to think that maybe life is too short to be doing this!

Anyone got any ideas?

Thanks x

Usually says on the bags how many litres. Why bother, though. If you thought they were a bargain then they probably were.
