- Only a few small countries (some Caribbean nations heavily influenced by America), have not formally adopted the use of SI.
- The USA is the only significant holdout.

Do most countries use metric system?
Yes, most countries around the world use the metric system as their standard system of measurement. The metric system is a decimal-based system that is widely adopted in many countries for its ease of use and consistency.
What countries use both the metric and customary system?
The United States is one of the few countries that officially uses both the metric and customary system of measurement. Myanmar uses a combination of both systems as well.
Are all metric units also system international?
No, not all metric units are part of the International System of Units (SI). The SI is a coherent system of units derived from the metric system, but it is more specific and defined, and not all metric units are included in the SI.
What countries use metric system and what countries use customary system?
Only the U.S.A. uses the customary system. Myanmar(Burma) and Liberia both use the old UK Imperial system, which uses the same names for units as the customary, but assigns them different sizes. The whole of the rest of the world uses metric.
Why metric system is wide used?
The metric system is widely used because of its simplicity, consistency, and ease of conversion between units. It provides a uniform system of measurement that is used internationally, facilitating communication and trade between countries. Additionally, the decimal nature of the metric system makes calculations and conversions straightforward.
