Freight may be calculated in a number of ways, depending on the individual contract. The principal distinction is between the weight of a cargo and its measurement. Generally, carriers aim to earn freight on whichever calculation (out of the weight or the cubic measurement) brings the greatest revenue.Thus very often freight is quoted on a weight or measurement basis, also called weight or measure. In this case, the rate of freight is multiplied by whichever is the greater, the number of cubic metres or the number of tonnes. This method of quoting freight applies particularly in cases where the ratio of a cargo’s weight to its volume (its stowage factor) is not certain.
