Gallons of water per metric ton A metric ton (1000 kg) of water occupies exactly one cubic meter. One cubic meter is 264.17 gallons.
For practical purposes the displacement ton (DT) is a unit of volume, 35 cubic feet (0.9911 m3), the approximate volume occupied by one ton of seawater (the actual volume varies with salinity and temperature). It is slightly less than the 224 imperial gallons (1.018 m3) of the water ton (based on distilled water).
