THE QUESTIONS




THE ANSWERS

  • BACKGROUND INFORMATION

    • Which units of quantity are used in Trade Map?


      The mostly used quantity unit in Trade Map is the metric ton (1,000 kilograms (kg), i.e. about 2,204.6 pounds (lb)). A few products, like electrical power, by nature cannot be expressed in tons. Some countries do not always report their quantities in weight (kilograms or tons). This is why Trade Map offers the following units:
      • kilometres
      • Thousands of square metres
      • Cubic metres
      • Megawatt hours
      • Units
      • Pairs
      • Dozens
      • Thousand units
      • Million units
      • Number of packs
      • Carats
      To analyze trade better, on the top of weight some countries report a second quantity unit. In this case, quantities expressed in this secondary unit can be found in Trade Map by choosing a "Time series" table showing "Quantities" not expressed in "Primary unit" but in "Supplementary unit" instead.
