The two main differences are simplicity and universality.
The metric system is much simpler since any measure of a particular characteristic is related to other measures of the same characteristic by powers of 10. With the US (or Imperial system, there are a huge number of conversion factors. For example:
Also, units for different characteristics are also linked by simple factors. For example, a hectare (area) = 10,000 square metres, or 1000 litre = 1 cubic metre.
In terms of universality, all countries in the world with the exception of the recalcitrant three: US, Burma and Liberia, plus some island states, have adopted the metric system.
The teaspoon is a traditional customary measurement that has been standardized in manufacturing practice and in food service / food labeling to equal an exact metric equivalent. In the United States one teaspoon as a unit of customary culinary measure is 1⁄3 tablespoon, that is, 4.92892159375 mL; it is exactly 1⁄3 US fluid drams, 1⁄6 US fl oz, 1⁄48 US cup, and 1⁄768 US liquid gallon and approximately 1⁄3 cubic inch. For nutritional labeling on food packages and in food service in the US, the teaspoon is defined as precisely 5 mL, the tablespoon as 15 mL. Almost ALL less expensive teaspoon measures sold in the US since the late 1950's have held an exact 5mL (overseas manufacturing is metric and they simply rounded up) - so you have been likely using the metric system for many years thinking you were using a customary measure without knowing it!
well the USA is the only country in the world to use the customary system while the rest of the world uses the metric system
We, who do not live in the US don't!
The customary system of weights and measures is now customary in a grand total of 3 countries: Liberia, Myanmar, and the US of A.
There are two main systems of measurements in mathematics, metric and US standard. Metric measurements are terms like centimeters, and US standard includes inches and feet.
The US has not converted to the Metric System yet. We are still using the English Customary.
The customary units are ones we use everyday. metric units usually have the word meter on it. my teacher taught me meter metric no meter no metric.
Yes they do use only the metric system
The unit of mass, the kilogram, is a part of both the US customary system and the metric system. In the US customary system, pounds are used for mass measurement, while the metric system uses kilograms.
The unit of length, meters, belongs to both the US Customary System and the metric system.
Outside the USA everything is metric. Come, join us in the modern world.
The SI unit is a Newton. The old US unit is the pound-force or the poundal.
In the US, inches. In metric countries, CMs.
One US gallon of producer's milk (not skimmed, semi-skimmed, homogenised etc), weighs 10.1 pounds-force in customary measure and 44.5 newton in metric measure.
Because the metric unit is used in the rest of the world. We are perhaps the only country with our own customary unit system.
No, Foot belongs to the Imperial and US customary units (according to Wikipedia)
The ounce is a unit of measurement used in customary systems, particularly in the United States and other countries that follow the imperial system. In the metric system, the equivalent unit for measuring weight is the gram.
