Why The USA Doesn't Use The Metric System

Why Does the U.S. Still Use the Imperial System?

Overview of Measurement Systems

• The video introduces a map showing countries that use the metric system versus those using the imperial system, highlighting that the U.S. is one of only three countries still using imperial measurements.

• The speaker reflects on their experience living in Germany and acknowledges that the metric system is more logical and sensible than the imperial system.

Historical Context of Measurement Systems

• The discussion begins with a brief history, noting that the British used the imperial system, which was adopted by America as a former colony. This historical context sets up why America continues to use it today.

• Thomas Jefferson, as Secretary of State post-independence in 1776, had an interest in adopting the metric system from France but faced challenges due to political instability during the French Revolution.

Adoption Challenges

• By mid-1800s, France stabilized and promoted its metric system; however, America's industrial growth led to resistance against switching systems due to existing infrastructure built around imperial measurements.

• In 1875, despite signing the treaty of the meter alongside 16 other countries, American industrialists opposed conversion due to potential costs and complications associated with changing established systems.

Legislative Attempts for Metrication

• A chart illustrates global adoption timelines for metrics; Britain switched in 1960 primarily for trade reasons—this influenced America's decision to stick with imperials initially.

• In 1971, Congress published "A Metric America," recommending a transition within ten years; however, by 1975 under President Gerald Ford's administration, conversion became voluntary rather than mandatory.

Modern Resistance and Cultural Factors

• Some companies voluntarily transitioned to metric but did not see widespread success; fears arose after Canada’s costly billion-dollar switch deterred further attempts in America.

• A notable moment occurred in 2016 when presidential candidate Lincoln Chafee proposed embracing internationalism through metrication but was met with ridicule instead of support. This highlights cultural resistance towards change even when practical benefits are presented.
