The National System of Units, often referred to as the metric system, is a standardized system of measurement used globally for scientific and everyday purposes. It is based on the International System of Units (SI), which includes fundamental units such as the meter for length, kilogram for mass, and second for time. This system promotes consistency and accuracy in measurements across various fields, including science, engineering, and commerce. Its adoption facilitates international communication and collaboration.

The system of units used in the United States is called the United States customary units or US customary units. This system includes units such as feet, pounds, and gallons.
The system of units used for measurements in chemistry is called the International System of Units (SI). It is a globally recognized system that provides a consistent set of units for measuring physical quantities.
The National Electrical Code (NEC) primarily uses the International System of Units (SI), which includes metric units such as meters, volts, and amperes. However, it also incorporates some customary units, particularly in areas like wire gauge and certain electrical measurements. This dual approach ensures clarity and consistency in electrical installations across the United States. Overall, the NEC aims to promote safety and standardization in electrical design and installation practices.
The term that describes the metric system units used in scientific data is "SI units" (International System of Units). These units provide a standardized system for scientific measurements, facilitating consistency and accuracy in data analysis and communication.

Metric units originated from France. During the 1790s, the National Assembly of France requested that the French academy of Science create a new system, one that was accurate and standard to be used.

Standard units are used for measurmen as there is a system called the SI units and that is considered as the international system of units that is why we use standard units for measurment .
The units of measurement for electric charge in the International System of Units are coulombs.
Of all countries in the world that has an officially established system of measurement, only Burma/Myanmar, Liberia and the United States do not use the International System of Units (SI). The United States use Imperial units and U.S customary units. That is not to say that SI is not in use in the U.S. The customary units are nowadays defined from SI units. And the National Institute of Standards and Technology uses it. To answer your question: the metrication of the United States is gradual and there is no fixed date where you can say that the US adopted SI. http://en.wikipedia.org/wiki/Metrication_in_the_United_States
