The Metric System.
The unit of length, meters, belongs to both the US Customary System and the metric system.
The US has not converted to the Metric System yet. We are still using the English Customary.
The unit of mass, the kilogram, is a part of both the US customary system and the metric system. In the US customary system, pounds are used for mass measurement, while the metric system uses kilograms.
The only unit that appears in both the modern SI (metric) system and the old fashioned system is the second.
Only the US uses the metric system. Hope it helped :D
Every civilised country in the world uses the metric system.
