Aluminum Sheet Sizing: Imperial vs Metric
Updated : Feb. 18, 2024When it comes to the dimensions of aluminum plates, we cannot ignore the two measurement systems: Imperial and Metric. For those unfamiliar, the conversion between these two systems can indeed be confusing.
However, in the practical application of aluminum plates, precision in dimensions is crucial. This not only involves the actual use but also relates to the quality and performance of the aluminum plate.
Understanding the differences between these two measurement systems is essential for anyone involved in the aluminum industry.

Countries and regions that use imperial measurements
Globally, the vast majority of countries have adopted a measurement system, but there are exceptions.
For example, the United States and its former colonies Liberia and Burma primarily use the Imperial system. The United Kingdom and its overseas territories, as well as Canada, use both systems.
