If business is now a global affair, then the export-import business is important, lucrative and necessary. An export-import agent is not a broker --- the agents are lower on the business totem pole.
Most properties are measured using a number and a unit of measurement. The unit of measurement is a standard amount. The number compares the property to that standard amount. This means a tree that is ten times as tall as a meter stick is 10 meters tall.
The metric measurement is a system of measuring using the liter, the gram, and the meter as basic units. The gram is used to measure mass or weight. For instance, a person weighing 170 pounds in customary measurement, weighs 77110 grams or 77.11 kilograms in the metric system. the liter is used to measure capacity. For instance, 1 liter of coke measures about 33.81 ounces in customary measurement.
