A cubic meter is a unit of volume
A ton is a unit of mass
So there's no way to convert them (unless you give a specific substance, that is, you know the density of that substance)
However, under normal temperature and pressure, one cubic meter of water is one ton

Most grains (rice, flour) are less dense than water, so most grains are more than 1 ton per cubic meter
