Why Does the USA Still Use the Imperial System Instead of Metric?
Explore why the USA continues using the imperial system due to historical roots and practical challenges in switching to metric units.
Video transcript
The USA sticks to the imperial system mainly due to historical reasons and practical resistance to change. When the metric system was introduced in the 18th century, the USA had already established its infrastructure using imperial units. Switching to metric today would involve significant cost and effort in changing signs, manuals, machinery, and education, which has led to continued use of the imperial system.
