How do you covert m3 to ton?

Answer 1

You cannot!!!!

Because 'm^(3)' is 'cubic metres' ; the metric VOLUME.

'Ton' is the 'Imperial' measure of 'Mass/Weight'.

The only connecting equation is

density = mass/ volume.

So without knowing the substance and its density , it is impossible to convert mass / to volume.

Answer 2

Multiply by the 'specific gravity'. It is 1 for water, so 1 m3 weighs one ton.

Oil is less dense, specfic gravity could be 0.7 or 0.8.

Rock is denser, specific gravity perhaps 5.
