∙ 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.

∙ 10y 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.

What units does the US use to measure distance?
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.
When did US adopt the metric system?
Of all countries in the world that has an officially established system of measurement, only Burma/Myanmar, Liberia and the United States do not use the International System of Units (SI). The United States use Imperial units and U.S customary units. That is not to say that SI is not in use in the U.S. The customary units are nowadays defined from SI units. And the National Institute of Standards and Technology uses it. To answer your question: the metrication of the United States is gradual and there is no fixed date where you can say that the US adopted SI. http://en.wikipedia.org/wiki/Metrication_in_the_United_States
