Ton-Mile

Ton-mile is a unit of measurement used to describe the transportation of cargo over a distance. It is calculated by multiplying the weight of the cargo by the distance it is transported. For example, if 10 tons of cargo are transported over a distance of 100 miles, the total ton-miles would be 1,000 (10 tons x 100 miles). Ton-mile is an important metric for calculating the efficiency of transportation and can be used to compare the cost and environmental impact of different modes of transport.
