After knowing the area, two more steps are required:
1) Detrmine the thickness, so you can calculate volume. Be sure to convert thickness to meters (it will be a small decimal) so volume is in cubic meters.
2) Find the density of the stone you are using in kilograms or metric tons per cubic meter and multiply.
The density of stone varies somewhat according to type, what quarry it comes from, etc.

Re: Convert area (m2) to weight (Kg or tonnes)

Embodied energy for timber MJ/kg to MJ/m2

and

concrete MJ/kg to MJ/m2

To work out the difference between production (MJ/kg) and assembly (MJ/m2)

A rough estimate would be appreciated

Crushed rock has a density of approxmately 120 lbm/cubic foot.

You have 180 * 3 * 1 = 540 cubic feet.

Converting to mass, 540 ft^3 * 120 lbm / ft^3 = 64,800 lbm

With 2000 lbm per ton, you would need:

64,800 lbm * 1 ton/2,000 lbm = 32.4 ton of crushed rock.

Megajoules and weight are totally different units of measure. They can not be directly converted from one to the other.
