Q Which measurement system is better? Give your own opinion. Metric System vs. Imperial System The metric system and the imperial system are two different measurement systems for things like distances, volumes, and weights. Since not all countries in the world use the same measurement system, it’s important to understand both. The metric system is a decimal system of units based on the meter as a unit length, the kilogram as a unit mass, and the second as a unit time. The imperial system is a system of measurement in use in the United Kingdom and other Commonwealth countries consisting of units such as the inch, the mile, and the pound. Since so many countries use the metric system, it might leave you wondering, “Who still uses the imperial system?” Only three countries in the world use the imperial system of measurement exclusively: Liberia, Myanmar, and the United States. Specifically, the measurement system used in the United States is also called the (U.S.) customary system. Actually, the only difference between the imperial system and the (U.S.) customary system is in a few volume measurements. Why doesn’t the U.S. use the metric system? When the metric system first started to be used, all industries in the U.S. were already set up using the imperial system. Therefore it would take a lot of time and money for businesses, manufacturing plants, and the country’s infrastructure to change course. Switching an entire country to the metric system can take decades.
