Do people use the metric system?
Overall, only 36% of respondents gave correct answers for U.S. customary units, but 71% did so for metric units.
According to the U.S. Central Intelligence Agency's The World Factbook (2023), the only countries that have not fully adopted the metric system are Myanmar, Liberia, and the United States.
Answer and Explanation: About 95 percent of the people in the world live in countries that have been 'metricated. ' This means these countries have officially adopted the metric system as their system of measurement.
The biggest reasons the U.S. hasn't adopted the metric system are simply time and money. When the Industrial Revolution began in the country, expensive manufacturing plants became a main source of American jobs and consumer products.
Americans also skew imperial on short distances, though younger adults are more metric-curious. While 86% of Americans say they would use yards, feet, and inches, just 8% would use meters and centimeters. About one in seven 18- to 44-year-olds (15%) say they would use meters and centimeters.
Only three countries – the U.S., Liberia and Myanmar – still (mostly or officially) stick to the imperial system, which uses distances, weight, height or area measurements that can ultimately be traced back to body parts or everyday items.
This almost universal standard allows you to understand measurements—and be understood—no matter where you are. The metric system is also easier to use because of the logical way the measurement units relate to one another.
Metric is simply a better system of units than imperial
In other words, it fits together very well and calculations are easy because it is decimal. This is a big advantage for use in the home, education, industry and science.
Metrics are numbers that tell you important information about a process under question. They tell you accurate measurements about how the process is functioning and provide base for you to suggest improvements.
94.7% of the world's population. 97.9% of the Earth's surface area.
Why do hospitals in the US use the metric system?
Healthcare workers use metric measurements to perform tasks like keeping accurate records, determining medication dosages and fitting patients for prosthetics and braces.
The expense of the U.S. changing over to the metric system translates into changed measurements on all packaged products, starting with food. The change would also impact housing and lot sizes, the measurement of temperatures with the new use of Celsius, and the change of mileage and speed signs.

In 1975, the United States passed the Metric Conversion Act. The legislation was meant to slowly transition its units of measurement from feet and pounds to meters and kilograms, bringing the US up to speed with the rest of the world. There was only one issue: the law was completely voluntary.
As such, there are only three countries in the world that do not use the metric system; the U.S, Liberia, and Myanmar.
II § 205a et seq. The Metric Board was abolished in 1982 by President Ronald Reagan, largely on the suggestion of Frank Mankiewicz and Lyn Nofziger.
Only a small handful of countries (Burma, Liberia, and the US) don't have the metric system as “official”. Even the US system is officially referenced to metric standards.
Mexico uses the metric system of weights and measures (as opposed to the Imperial system, which is what Americans use).
Metric System is Easier to Use
You can convert millimeters to meters dividing by 1000 (10 power 3) and after calculating the square meters or cubic meters, you do not require further conversions. Similarly, kilograms can be converted to metric ton simply dividing by 1000 (10 power 3).
John Wilkins, an English clergyman, and brother-in-law to Oliver Cromwell, first wrote about it two years before Gabriel Mouton, who is considered by many to be the founding father of the metric system. In 1670, Mouton proposed a decimal system of measurement that French scientists would spend years further refining.
Difficult to Use With Fractions
The only major disadvantage in using the metric system is that it's not well-suited for working with fractions. For example, 1/6 meter is approximately equivalent to 167 millimeters and 1/3 kilogram is approximately equal to 333 grams.
How expensive would it be to switch to the metric system?
Using Canada's cost data, the United States conversion could cost about $334 million. However, this estimate could vary depending on the length of implementation and the replacement method chosen. using metric speed limits, distances, or other measurements.
People in the US and UK mainly are still using the imperial system because they are used to it, and it makes sense for them. If you tell them that the temperature today is 40 Celsius, it never makes sense for them, as you would say it is 104 Fahrenheit.

A business success metric is a quantifiable measurement that business leaders track to see if their strategies are working effectively. Success metrics are also known as key performance indicators (KPIs). There is no one-size-fits-all success metric; most teams use several different metrics to determine success.

The metric system is commonly referred to as the International System of Units, as it is used by virtually all countries in the world. Interestingly, three countries in the world do not use the metric system, despite its simplicity and universal use. These are Myanmar, the United States, and Liberia.
The metric system is the most widely used measurement system in the world; it is also the primary measurement system used in the medical field. Healthcare professionals, including medical assistants, must have the ability to convert units of measurement within and between the metric and US customary systems.
Answer and Explanation:
There are two possible reasons that not using the metric system in the U.S. is dangerous for health. Medication dosages are often presented in the metric system, which means that either metric tools are needed to measure out a dose or a conversion needs to be made.
After the U.S. gained independence from Britain, the new American government decided to keep this type of measurement, even though the metric system was gaining in popularity at the time. We are one of the few countries in the world that still use this system, and first-time visitors can find it confusing.
The effort toward national metrication is based on the premise that the U.S. industrial and commercial productivity, mathematics, and science education, and the competitiveness of its products and services in world markets would be enhanced by adopting the metric system.
Did the U.S. ever try to switch to metric?
In 1975, Congress passed the Metric Conversion Act, which declared metric as the preferred system of the United States, and the U.S. Metric Board was created to implement the conversion.
There was a specific time in history when America did consider taking up the metric system. But pirates intercepted the standards, and America has refused to change its measuring system ever since. Way back when America was still a new country, there was no regulated measuring system throughout the states.
Canada follows the International Metric System. Temperatures, rainfall measures, distance, weights, velocity are expressed in metric units. Distance is measured in kilometres.
Officially, China is on the metric system, though the traditional Chinese measurements are still commonly used in everyday life. Below are the most common measurements in both systems. Sometimes the character for the measurement is found in both the Chinese and metric systems.
Canada made its first formal switch from imperial to metric units on April 1, 1975. That was the first day weather reports gave temperatures in degrees Celsius, rather than Fahrenheit. Many did not take kindly to the change.
The Imperial measurement system was first developed in Britain in the 1800's and replaced the Winchester standards which had been in place since the late 1500's. The Middle Ages provided the background for development of the British System.
Jefferson rejected the metric system, however, because in origin he found it to be too French—which was saying something coming from the nation's foremost Francophile. His beef was that the meter was conceived as a portion of a survey of France, which could only be measured in French territory.
The basis of the argument is that while the metric system of units is based on scientific constants, the imperial system is based on the size of everyday items. From Real Clear Science: While the metric units' association with physical constants makes them accurate, it makes them less practical for common use.
Already NASA, US Army and others use the metric system, and Celsius degrees instead of Fahrenheit. Do you not see the advantage with a system dividing by 10 instead of the imperial units?
94.7% of the world's population. 97.9% of the Earth's surface area.
How much would it cost to switch to the metric system?
Using Canada's cost data, the United States conversion could cost about $334 million. However, this estimate could vary depending on the length of implementation and the replacement method chosen. using metric speed limits, distances, or other measurements.

The Imperial standard meter, often shortened to meter, was an established unit of measurement for length used by the Galactic Empire. One meter equaled 100 centimeters, or 1000 millimeters, and was roughly equivalent to three feet.
Despite NASA's non-compulsory policy, commercial space manufacturer SpaceX currently designs its systems (e.g. Dragon and Falcon 9) using metric units.
Imperial units were used in aviation industry before and this industry was needed to built rocket parts. Astronauts were military and test pilots before, they were used to altimeters calibrated in feet. Aviation is still not full metric.
Today, the American public remains mostly on the side of US customary units. Polling from 2016 found that only 32% of Americans wanted to go metric.
Most scientific and technical apparatus will use the metric system. Particularly electrical engineers volts, amperes, watts, farads, henries are all metric. Still you encounter lots of general purpose stuff that is in imperial (actually we call the US Customary units) so you have to do a lot of conversions.
The question in the title of the article asks which countries use the metric system — more accurately called the International System of Units — but it would be much easier to list which countries don't use it. There are only three: Myanmar (or Burma), Liberia and the United States.
