Assuming you are talking about 'tons' (2,000 pounds) then there is no answer to your question.
As an example, if the the cubic meter was filled with hydrogen or helium gas, it would be lighter than air even is, and it would rise up and up toward the sky.
A cubic meter of feathers might weigh a few pounds, while a cubic meter of water would weigh nearly a ton. (2,000 pounds).
Imagine how much a cubic meter of heavy lead would weigh!
Assuming that you mean a ton, there can be no conversion.
A ton is a measure of mass. A cubic metre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
There is no general conversion, since a ton is a measure of mass, and a cubic meter is a unit of volume. It depends on the density of the substance you are talking about.
No cubic decimeters are in a meter. There are 1000 cubic decimeters in 1 cubic meter.
1 meter = 10 decimeter 1 cubic meter = 1000 cubic decimeter
There are 35.3147 cubic feet in 1 cubic meter.
1 liter = 0.001 cubic meter 1 cubic meter = 1,000 liters
1 cubic meter is 1.308 cubic yards.
Since 1 cm = 0.01 meter, 1 cubic cm = 0.013 cubic meter. (1/1,000,000 of a cubic meter)
1 cubic meter ≈ 35.3146667 cubic foot
1 cubic meter is 1,000 cubic decimeters.
Your 1 cubic meter = 1.30795 cubic yards.
1 cubic meter = 61,023.7441 cubic inches.
1 (cubic meter) = 35.315 cubic feet.
