Level of Metric Adoption

Despite global calls for standardization in measurement, only a handful of countries have fully adopted the Metric System, labeled in recent years as the International System of Units (SI). Developed in France during the late 18th century, the metric system marked an effort to simplify measurements and unify them globally.

- Countries like South Korea, Brazil, Japan, Sweden, and Mexico have 'complete' adoption of the metric system, but interestingly, they also retain a few non-metric units for specific or everyday purposes.
- In contrast, North Korea, Canada, Trinidad and Tobago, the United Kingdom, Myanmar, Jamaica, Liberia, and the United States have only 'partially complete' conversion to the metric system. Additionally, for many of these nations, the transition has stalled, suggesting cultural, political, or logistical barriers to complete adoption.
- A group of countries including China, Indonesia, Malaysia, Philippines, Taiwan, Sri Lanka, Ireland, Peru, Thailand, Hong Kong, and Macau are approaching 'almost complete' adoption of the metric system.
