Explanation:
Detailed explanation-1: -You can convert directly by multiplying gravimetric moisture content to bulk density of soil. i.e. volumetric moisture content = gravimetric moisture content * bulk density of soil.
Detailed explanation-2: -To measure soil moisture content by the gravimetric method, a subsample of a fresh, sieved composite sample or a fresh soil core is weighed, oven dried until there is no further mass loss, and then reweighed. The moisture content is expressed as mass of water per mass of dry soil.
