en van een andere site;R/T - A unit measure used in marine transport to compare the volume and weight of a shipment. Freight rates are usually expressed in terms of cost per revenue ton. There are three different formulas in general use for determining the total number of revenue tons in a given shipment when the freight is calculated on a weight or measurement basis:
The greater of the total number of cubic meters versus the total number of metric tons;
The greater of total cubic feet/40 versus the total gross weight in pounds/2.000;
The greater of total cubic feet/40 versus the total gross weight in pounds/2.234.
O.N. zal inderdaad wel een 1 of ander serienummer zijn.A Revenue Ton (RT) is a shipping term describing the measurement on which the shipment is freighted. If cargo is rated as weight or measure, whichever produces the highest revenue will be considered the revenue ton. Weights are based on metric tonnes and measures are based on cubic meters.
1 RT = 1 tonne or 1 m3
