1cubic meter how many kg?

Answer 1

There can be no conversion.

A kilogram 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.

Answer 2

The weight of 1 cubic meter depends on the material. For example, water has a density of 1000 kg/m³, so 1 cubic meter of water would weigh 1000 kg. Other materials have different densities, so you would need to know the specific material to determine the weight of 1 cubic meter.

Answer 3

For this calculation the specific weight (density) of the material in question is needed. In the case of pure water :- 1 cubic meter weighs 1 tonne or 1000 kilograms.

Answer 4

this is impossible as the units do not fit each other
