11 Countries That Use the Imperial System in 2024

Have any Americans ever visited to Europe and found themselves oblivious to the measurement of a drink’s liters? Or is there a difference in the shoe size? Perhaps the person you matched with had a height measured in centimeters? You’re in a state of confusion and frenzied app conversion on your phone.

The majority of the world’s population measures things using the metric system. Very few people make use of the Imperial system. With the passage of the Weights and Measures Act in 1824, it was initially implemented in Britain and quickly expanded throughout the British colonies. But by the year 2000, the majority of nations—including many of Great Britain’s measurements—had switched to the metric system. There are still some nations that use the Imperial system to some or all aspects of their government. Let’s examine the eleven nations that will still employ the Imperial System in 2024.

United States

Because of Great Britain, the United States adopted the units of measurement that it uses today. This was implemented in 1832 but did not take into mind the British Imperial System shift. As a result, the US has a system known as “American customary unit.” Nonetheless, there are a lot of measurement units that are comparable to the Imperial System. The government was directed to adopt the metric system for US trade and commerce by the Metric Conversion Act of 1975, and this system is still in use today.


Liberia adopted the Imperial System and has never switched to the metric system of measurement because it was formerly an American colony. Despite their announcement in 2018 that they will begin the transition to the metric system, the Liberian government has not yet implemented this shift.

United Kingdom

The United Kingdom adopted the metric system in the middle of the 1980s, and corporate sectors are the primary users of this system. Although there are certain applications that can only utilize one or the other, both the Imperial System and the Metric System are used in tandem. Road signs, ciders, and beers are all on the Imperial System. Many British citizens still prefer to utilize the Imperial System over the metric system.


The countrywide use of the Imperial System was gradually replaced in the 1970s with the metric system. But the pace of metrification has been modest, probably because of its closeness to the US. Even though the government has moved to the metric system, Canadians continue to utilize the Imperial System on a daily basis.


In the middle of the 1950s, India began the transition to the metric system. It was announced that the metric system would replace all other measurement systems by 1962. That is the standard measurement method used today, while Indians accustomed to the Imperial System may continue to use it in their daily life (not for official purposes).


Only three nations, including Myanmar, do not use the metric system as their official weight and measure system. But the Burmese government chose to gradually switch to the metric system in 2011. By 2019, everything was supposed to be switched to the metric system, but that deadline was missed.

Hong Kong

In Hong Kong, metric units have been used for all government measurements since 1976. As of 2012. The British Imperial System, Chinese units of measurement, and the metric system are all in use in society and non-governmental contexts. Because the British ruled Hong Kong from 1841 until 1997, the Imperial System was in place.


Although metrification is widely utilized in Australia, the imperial system is still applied in a few places. For instance, Imperial fluid ounces are used in the sale of beer and cider. Inches are typically used to measure screen sizes. The Imperial System is also used to measure barrel lengths for firearms, property, and navigation. The Imperial System is still frequently used in informal conversations.


Ireland used the Imperial System extensively since it was a part of Great Britain. It had used the Imperial System ever since gaining independence, but after entering the EU, it gradually began to embrace the metric system. Metric road signs and speed limits were introduced in 1997 and 2005, respectively. But pubs continue to utilize Irish trains, property listings, and the Imperial System.

New Zealand

As a colony of Great Britain, New Zealand was subject to the imperial system across its territory. In order to metrify everything but the aviation sector, the nation adopted the metric system in 1976. When navigating at sea, they also use nautical miles. The only devices where inches are still utilized are computers, phones, and television screens.


The imperial system was extensively employed since the Bahamas, an island republic in the Caribbean, was a British colony. The Weights and Measures Act, enacted by the Bahamas government in 2006, declared that both the imperial and metric systems would be accepted. As a result, the imperial system is still in use across the islands.
