what is the difference between tonnes and tons
Tweet. Key Difference: Ton is a measurement unit that is generally used for weight. In U.K., one ton is equivalent to 2240 pounds and in the U.S.A., it is considered to be equivalent to 2000 pounds, whereas a metric ton is used to denote 2204.6 pounds.
In Britain for example, prior to the introduction of the SI system, the ton that was used was equal to 2240 pounds (1016kg), and since this value is very close to actual metric tonne (1000kg), people felt very little difference between the earlier ton and the metric tonne.
