대통령 선거에 실패한 그의 전 로드아일랜드 주지사(및 상원의원) Lincoln Chafee는 미국이 다른 측정 시스템을 수용해야 한다고 주장했습니다. Chafee 는 2015년 캠페인 런칭에서 " 대담하게 행동합시다. 다른 세계에 합류하여 미터법으로 가자 " 고 선언했습니다.
그 사건은 이전에 만들어졌다.
Some readers might recall the U.S. Metric Conversion Act of 1975. Signed into law by then-President Gerald Ford, it declared "a national policy of coordinating the increasing use of the metric system in the United States."
But there was a major caveat. To quote Ford himself, this legislation was "completely voluntary." Since it didn't require anyone to switch over to metric measurements, most of his countrymen didn't bother.
Still, the rest of the world (apart from a few other countries) uses metric so there's bound to be times you have to convert kilograms to pounds, and vice versa.
Pounds are a means of measuring weight. Devotees of the metric system use kilograms to measure a related — but distinct — phenomenon: mass.
In spite of this inconsistency, you often hear "kilograms" and "pounds" mentioned in the same breath. Today, we'll show you how to convert one into the other.
Converting Kilograms to Pounds (The Textbook Way)
Here's an important figure to remember (if you can): 2.2046
See, 1 kilogram is equal to 2.2046 pounds. So, to make a conversion between the two measurements, you'll need to use this number.
Let's say your Canadian friend Bob tells you his dog Rex weighs 34 kilograms. What does that mean in terms of pounds?
Unfortunately, the formula isn'tquiteas simple as just taking the relevant amount of kilograms and multiplying it by 2.2046. But don't worry; it's still pretty darn simple.
First, we must write down two separate fractions: 34 kilograms divided by 1 and 2.2046 pounds divided by 1 kilogram. Then, we'll have to multiply the former by the latter.
Here's what that equation looks like when expressed numerically:
(34 kilograms/1) x (2.2046 pounds/1 kilogram)
The division by 1 might seem pointless. But we need it to do our conversion. Note that the "kilograms" notations in those two fractions will cancel each other out. But the "pounds" notation? That's not going anywhere. Ergo, we're left with:
(34/1) x (2.2046 pounds/1)
Like they taught us in grade school, a number divided by 1 equals itself. With this knowledge in mind, we can now rewrite our equation like so:
34 x 2.2046 pounds = 74.96 pounds
Therefore: 34 kilograms is equal to 74.96 pounds, or 75 pounds, rounded up.
Yeah, it's probably safe to assume Rex isn't lap dog material ...
Converting Kilograms to Pounds (the Quick Way)
Let's say you're not in math class any more. You just want to know approximately how much Bob's darn dog weighs in pounds and right away.
34에 2.2를 곱하면 됩니다. 이것은 74.8파운드를 줍니다. 충분히 닫습니다.
또는 편리한 계산기가 없는 경우 :
- 킬로그램에 2를 곱합니다.
- 합계를 구하고 소수점 자리를 왼쪽으로 한 칸 옮깁니다.
- 두 숫자를 더합니다.
다음과 같이 표시됩니다.
- 34 x 2 = 68
- 소수점 이하 자릿수를 한 자리 왼쪽으로 이동하면 6.8이 됩니다.
- 68 + 6.8 = 74.8
파운드를 킬로그램으로 변환
자, Rex의 무게를 파운드로 설정했으면 역 접근 방식을 취하겠습니다. 파운드를 킬로그램으로 어떻게 변환합니까?
기술은 비슷합니다. 다시 한 번 분수에 다른 분수를 곱할 것입니다. Rex의 체중이 68파운드라고 가정해 보겠습니다.
새로운 공식은 다음과 같습니다.
(68파운드/1) x (1kg/2.2046파운드)
이번에는 두 개의 "파운드"가 서로 상쇄됩니다. 이제 다음이 남았습니다.
(68/1) x (1 kilogram/2.2046)
And hey, since we've got a number divided by one here, it's possible to simplify things a bit.
68 x (1 kilogram/2.2046)
Pause! Take a look at everything between those two parentheses. What's 1 kilogram divided by 2.2046?
Why 0.45 kilogram, of course. So now, we've got:
68 x 0.45 kilogram = 30.6 kilograms
The quick way? Just divide 68 by 2.2. You'll get 30.9 kilograms.
Now That's Interesting
Believe it or not, the United States Mint is metric system-dependent. As Elizabeth Benham writes on the National Institute of Standards and Technology's official website, American "coins & currency are produced using metric specifications."
