They already have.
this means start the new system instead of the old system
People needed a way to measure things
so everyone around the world can understand it.
President Thomas Jefferson attempted to introduce a decimal system similar to the metric system in the United States during his time in office. However, the initiative did not gain widespread adoption by the American public.

South Africa "Metricated" between 1971 and 1973. In other words, the system of weights and measures was changed from the Imperial (British) system, to the Metric system South Africa "Decimalised" in 1961. In other words, the currency was changed from the Imperial (British), to the Decimal system.
The metric system came about during the time of the French Revolution, during the age of Rationalism etc. This places it in the later part of the 1700's, which is the 18th century. A good resource for this is the book "The measure of all things" by Ken Alder
They should start using ONLY metric units. It is high time that the United States starts using international units.
The Metric system was designed from the start to be simpler than older systems. Take length, for example. In the Imperial system, there are units like inches, feet, yards, rods, fathoms, miles. In the Metric system, there is just one unit of length: the meter. To get larger and smaller units, you use different prefixes, like kilo for 1000, Mega for a million, milli for 1/1000, etc. The point is, the prefixes used are the same for different units. Here are some other problems with the Imperial system. In the metric system, the unit for volume (cubic meter) is directly related to the unit of length (the meter). In the Imperial system, the gallon is commonly used for volume, but it is unrelated to the unit of length. Cubic feet are also used, but unfortunately, the conversion factor between cubic feet and gallons is no simple number (like 1, 10, or perhaps 1000). Worse, different units for volume are used for dry volume (as for grains) and liquid volume.
Russia, as the Soviet Union, adopted the metric system in 1924. Since then, the official unit of measurement for temperature in Russia has been Celsius.
Fuel system should be where to start.
nope!
