How much gravel needed?

[fishlearn]

Hi,

Was trying to find something like this, but didnt managed to get anything.

Was wondering, is there any guide for gravel?

Gravel is sold in small 1kg packs and 5kg packs.
What size of pack would be enough for various sizes of tanks?

For example,
1 ft tank --- What size pack of gravel to buy to fill it?
1.5 ft tank --- What size pack of gravel to buy to fill it?
2 ft tank --- What size pack of gravel to buy to fill it?

Any experience to guide and share?
