how many meters are 512 liters?

1 litre is 0.001 cubic metres, so 512 litres is 0.512 cubic metres.

.

(This is probably a troll)

But...

They're different conversion rate, you can't measure between the two.

Unless you mean 512m of a cylinder/(any other container) filled with the liquid.

Then more information will be required.

the correct question is how many square meters are 512 liters?

Just as expected!

Alan would come with an answer that I didn't even know existed.
