Translation:In my country we use the metric system.
Moreover, the metric system has been the official system for weights and measures in the US for a long time. The commonly used units are then derived from the metric standard units. "Under the Mendenhall Order in 1893, metric standards, developed through international cooperation under the auspices of BIPM, were adopted as the fundamental standards for length and mass in the United States. The definitions of United States customary units, such as the foot and pound, have been based on metric units ever since." https://en.wikipedia.org/wiki/Metrication_in_the_United_States
