- measurement ton
- (MTON or MT)a unit of volume used for measuring the cargo of a ship, truck, train, or other freight carrier, equal to exactly 40 cubic feet, or approximately 1.1326 cubic meters. This unit was traditionally called a freight ton (see ton5), but that term now means a metric ton of freight in most international usage. However, the confusion seems impossible to dispel; some shippers are now using "measurement ton" to mean a metric ton of freight. (The way out of this dilemma is simple: measure volume in cubic meters and weight in metric tons.)
