∙ 14y agoThe US uses customary units for historical reasons, as these units have been in use for hundreds of years. Changing to the metric system would require a significant investment in time, money, and resources to re-educate the population and transition existing infrastructure.

∙ 14y agoThe only reason they're "customary" around here is because we continue to use them.
Once you get anywhere outside the US, the inch, yard, mile, and pound are no longer customary; they're just plain weird, and everybody there is asking the same question.

∙ 9y agoInformal units of measure include any type of measurement representation a person uses. A common informal unit of measurement is hand span (or hands) because hands are visual and measurements can be understood across all languages and cultures.

∙ 11y agoIt would make no sense to measure your height in seconds, or to talk of your age in kilograms! Different characteristics need different measures.
Different units are required so at to measure things on different scales accurately. You would not want to measure the distance from the earth to the sun in millimetres! The answer is approximately 150,000,000,000,000 mm. Conversely, you would not want to measure your height in kilometres: 0.0018 km approx, even less the thickness of a sheet of paper. You need a small unit to get an accurate result for a short distance and a large unit for a long distance.

Well, it is because early men did not need to make accurate comparisons. They could tell by looking whether a place was large enough for a family to live in.

∙ 10y agoBecause it is too hard for American teachers to understand SI units and teach them to children. The US has agreed to use SI units almost 20 years ago and is still struggling with it.

The system of units used in the United States is called the United States customary units or US customary units. This system includes units such as feet, pounds, and gallons.
The US is one of the 3 remaining countries that still use Imperial (old British) units to measure distance. They therefore uses feet, inches and miles. The rest of the world uses the international standard decimal units relating to the Metre.
Countries that do not officially use the International System of Units (SI) include the United States, Liberia, and Myanmar. These countries predominantly use the US customary system, imperial system, or their own traditional units for measurements.
No, Foot belongs to the Imperial and US customary units (according to Wikipedia)
Force is measured in units of newtons (N) in the International System of Units (SI) or pounds (lb) in the US customary system.
The US has their own way of measuring things, I guess, and there really isn't an explanation for it.
Use a conversion factor
square feet
use a conversion factor.
Customary Units
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.
Liter is used in the United States, but it is not one of the US customary units.
Use a conversion factor
US customary units
You need to find the conversion factor for the units in question.
Ounces and feet
A "fathom" is a measure of units in the British Imperial System, later derived for use in the US Customary System. It is approximately two yards (or six feet), and is most commonly used in measuring nautical distances.
