La presenza duratura del sistema imperiale nella tecnologia moderna

The Imperial system persists in technology despite the widespread adoption of the metric system due to historical entrenchment, economic barriers, and industry-specific inertia. In key economies like the U.S., Imperial units are deeply integrated into industrial infrastructure, from manufacturing machinery to engineering standards, making a full transition to metric prohibitively costly and logistically disruptive. Legacy sectors such as aerospace (e.g., altitude in feet), automotive manufacturing, and semiconductor production (e.g., 12-inch wafers) rely on Imperial measurements rooted in decades of established designs, supply chains, and global interoperability agreements. Cultural familiarity among professionals, coupled with risks of errors during transitions—famously illustrated by the 1999 Mars Climate Orbiter failure—further discourages abrupt shifts. Additionally, global market dynamics compel manufacturers to retain Imperial units for compatibility with U.S.-centric components and consumer preferences (e.g., screen sizes in inches). While the metric system dominates science and international trade, the Imperial system endures in technology due to entrenched practices, economic pragmatism, and the complex challenges of harmonizing global standards.
