How many tones are in 1 cubic meter?

Answer 1

Presumably the question is about tons, and not TONES which are about the quality of sound. However, the question, as stated, cannot be answered sensibly. A cubic metre is a measure of volume, with dimensions [L3]. A ton is a measure of mass, with dimensions [M]. The two measure different things and elementary dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.

As a simple mental exercise consider a cubic metre of air and of water. They will have very different masses.

Answer 2

There are 1,000 kilograms (1 metric ton) in 1 cubic meter.
