You are missing on vital item for you conversion. Cubic meters of WHAT? If you think about it, a cubic meter of feathers is going to be a lot lighter than a cubic meter of concrete. What you will need is a conversion factor - the Density - of the material. Usually this is called the specific gravity, and is in the units of grams per cubic centimeter.

If you'll let me know what you need to convert, I'll see if I can't point you to finding the specific gravity, and from their, the weight of the volume.

1 cubic meter of loose dry coarse river sand into pounds


On average, dry sand weighs approximately 60 pounds per cubic foot.
There are 27 cubic feet per cubic yard.
60 x 27 = 1620 pounds per cubic yard.
From this website, 1 cubic yard = 0.7646 m^3, so
1620 pounds per cubic yard x 0.7646 m^3/yd^3 = 1238 pounds per m^3
Use at your own risk as I am not a mathematician,
and as always, check my math!
Hope this helps.
