The unit that belongs to both the US and metric system is the meter. It is used to measure distance in the metric system and is also commonly used in the US for scientific and industrial purposes.
The US does not use the metric system.
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 metric system is used in many scientific fields and industries in the US, such as in laboratories, engineering, and international trade. However, the US primarily uses the Imperial system for everyday measurements like distance, weight, and volume.
The milligram is part of the SI system of measurements, it represents 1/1000 of a gram. One gram is the weight of one milliliter of pure water at 4 C. So the answer is no. The metric system is international, not US.

No. Congress can decide whether or not the metric system is adopted by the US, but the metric system exists and is used by developed countries whatever Congress choses to do.
The US does not use the metric system.
Meters are commonly used inside the metric system, while they're equivalent in the Imperial (US) system is called feet.
No, even the US uses the metric system (although we retain traditional units for many purposes). Even the traditional units used in the US use the metric system as their calibration standards (eliminating the older independant traditional standards). I have an 1877 Arithmetic schoolbook which has a section on using the metric system that was used in US grade schools at that time. (this copy was used by my grandmother and her sister when they were in grade school)

That depends wether you are in the metric system or the system used by the US. In the US the mesurtements are Ounces, Pints, Quarts, and Gallons
The metric system in universal around the world whereas the customary system is only used in the US. For this reason scientists and mathmeticians all use the metric system because it creates a sort of universal language so there is no translating.
A metric ruler typically measures length in millimeters or centimeters and follows the metric system, whereas a US ruler measures in inches and fractions of an inch following the imperial system. Metric rulers are commonly used in countries that follow the metric system, while US rulers are popular in the United States and other countries that use the imperial system.
The metric system is used for measuring anything and everything.
