Three countries in the world do not use the metric system as the official system of measurement: the United States, Liberia , and Myanmar. After independence, secretary of state Thomas Jefferson insisted on using the imperial measurement system despite Congress proposing to use the metric system. The metric system is used in the United States, but it is not the official system of measurement.
The government, however, is in the process of adopting the metric system. Myanmar isolated itself after gaining independence from Britain; therefore, it never required a common measurement system with the rest of the world. After using its own traditional forms of measurements, Myanmar is in the process of adopting the metric system now that it is open to the rest of the world. It is likely that the United States will soon be the only country in the world that has not fully adopted the metric system.
The imperial units of pints and gallons are one of the few remaining sets of units that differ between the U. The reason for this is that the British updated their definition of a gallon in , which the Americans declined to do — favoring instead the British wine gallon as defined in This means that the U. When factoring in the gallons of water in a water heater , for example, you need to be sure that you are using the correct measurement. In general, volumes listed in the United States will follow the U.
Like the 16 ounces in a pound, the reasoning behind the system of hours, minutes, and seconds is also based on simple math. The Babylonians regularly used base 60 in their numbers, because it can be divided by 2, 3, 4, 5, 6, 10, 12, 15, 20, or 30 leaving whole numbers. The Babylonians gave us the modern system of measuring time, as well as the division of a circle up into degrees.
Despite the efforts of the French Revolution and the Swiss company Swatch in , there has never been a successful development of metric time.
The current system of measuring time is one of the few instances of a truly global standard — wherever you go in the world, a minute is one-sixtieth of an hour, and there are 24 hours in a day.
The history of pressure measurement is linked to the development of heat-measuring technology. Since Galileo developed a tube to show changes in temperature by drawing water, scientists have demonstrated that pressure and temperature are intrinsically linked. In the seventeenth century, scientists created the first vacuum an area of no pressure and discovered the idea of air pressure since Aristotle scientists had assumed that air had no weight.
In the Imperial System, pounds per square inch is the most common unit of measurement. Throughout our home and daily lives, we regularly measure pressure.
Ultimately, whatever the systems of weights and measures in use in your country, there is a level of standardization that has existed for at least a century. Unlike our ancestors, we can order parts for a building project from anywhere in the world, safe in the knowledge that there is a shared vernacular of units.
Although the competition between the Metric and Imperial Systems continues, the ease of conversion between the two means that it presents few problems in daily life. The History of Measurement. Then we will have a truly global system of weights and measures.
The Imperial System The history of the imperial system goes back as long as humans have been measuring things.
Within the Imperial System, there are more units and subunits based on historical rationale. The Metric System In the aftermath of the French Revolution, many of the old orthodoxies were being challenged.
For example, 1 liter of water weighs 1 kg. This further standardized the metric system and created an international scientific standard. Why Imperial and Not Metric? No need to break out the measuring tape - just read on!
