米和平方米的换算公式是什么？

平年全年365天，闰年全年366天

平方米是面积单位，米是长度单位，换算关系为1平方米=1米×1米。

squarefeet换算平方米(平方米和feet换算)

长白山脉（满语转写：golmin xanggiyan alin），中华名山，是满族的发祥地和满族文化圣山 。早见于4000多年前的文字记载中，《山海经》称“不咸山”，北魏称“徒太山”，唐称“太白山”，金始称“长白山”。清朝时视之为神山，须亲自或委派大臣到吉林乌拉（今吉林）望祭长白山。

平方米（㎡，英文：square meter），是面积的公制单位。定义为边长为1米的正方形的面积。在生活中平方米通常简称为“平米”或“平方”。港台地区则称为“平方公尺”。

平方米是生活和工作中常用的计量标准。它是公制面积单位。它被定义为边长为1米的正方形的面积。在日常生活中，平方米通常被称为“平方米”或“平方米”，符号用平方米来表示。如果任意形状的平面的面积等于边长为1米的正方形的面积，也叫1平方米。

米用符号M表示。标准watt瓦特power功率W J/s规定了每间隔299792458真空中保持的光的长度。一平方米等于100平方分米，或10000平方厘米。

1平米是很好计算的，就是长度1米，宽度1米，那么长跟宽相乘，就是1平米。

其实在我们读小学的时候，就已经学习了关于面积计算的方法与公式，长方形和正方形的计算方法都一样，都是要看面积的长度和宽度是多少，然后长度跟宽度相乘即可把这个面积给计算出来。

那么现在我们要计算的是1平米的面积，那就等于是长度为1米，宽度为1米，1×1还是等于1，只是长度是米为单位，宽度也是米为单位，计算出来的结果是以平方米为单位。

不可数名词(uncountablenouns)是指不能以数目来计算，不可以分成个体的概念、状态、品质、感情或表示物质材料的东西。

Not far from Rizegou Guesthouse is the Swan Lake. It is said that swans used to reside here. At the present time, the lake remains semi-marsh land eith waterweeds fully covered on the surface. In spring the lake resembles a carpet of green grass; in summer the lake is splendidly decorated with blossomed flowers; in autumn the yelliwness in the lake meets the eye in every side; in winter the lake remains a world of ice and snow. Near the upper end of the lake is an another lake called Fangchaohai. The lake leads to hills where the hill peaks raise one higher than another. However, among the hills there is a pealk that obviously towers. It is named the Sword Rock because it looks sharp on the top and wide at lower part. Passing the foot of the towering peak, you start to walk into a dense primeval forwst, where you find yourselves deep in the boundless expanse of trdds and plants, feeling as light as if you had left the world of men and became immortal beings. There are an abundance of trees that looking up you hardly see the sunshine. Some of the trees curves down like awnings; some loom up like obelisks; some stand erect like men; some recline like dragons. Beneath your feet are soft mosses that grow in a thick furry mass on wet soil. When you walk through the forest, cool greenery rests your eyes, gentle breeze sooths your ears and the utter quietness refreshes your heart.

谁有长白山天池的英文啊?

我还连接了一篇就是天池的，也是百度看到的，你可以参考下～～～

以下是中英文对照的一片水怪报公顷：导～～

北京晨报9月3日 “‘怪兽’！天池又出现‘怪兽’了！”9月2日，一些国内游客和20多名韩国游客在吉林白山南坡旅游时，发现了在天池中游动的数只不明生物。

据长白山南坡景区管理有限公司司机李军介绍，2日上午他们拉着20多名韩国游客到长白山南坡旅游。9点多钟到达山顶时，天上云彩比较厚，有微风，天池中倒映着云彩和少许蓝天。

突然，他发现天池中靠近东部的湖中有波纹，开始以为是风，后来发现是一些黑点自北向南游来，在后面留下很长的波纹。他就喊：“快看，天池‘怪兽’出来了！”

现场总共有四五十名国内外游客，大家争相观看，一些人拿出相机拍照，他自己也用手机拍了照片，但很不清楚。

李军说，这些“不明游动物”越游越近，他看见了一些黑点，从望远镜里看是6只“怪兽”，根据比例测算，应该比人大，游速相当于普通人游泳的速度。它们分前后两组向南游来，快到天池岸边时，转向东坡方向游去。在离岸边大约100米处，前三个黑点消失在水下。十几秒后，后三个黑点游到前三个黑点消失处时，那里忽然翻了个大水花，出来个比这几个黑点大十几倍的大黑点，然后这些黑点同时消失，再没有出现。

据吉林省集安市云峰国旅导游崔永宽介绍，他带的这个韩国旅游团是从长春入境的，共有23人，其中柳焕日是摄影爱好者，带的是专业摄影设备，因此拍摄的怪兽照片比较清楚。崔永宽说，他也是次看到怪兽，非常清楚。这次怪兽出现总共有十五六分钟。

长白山南坡景区管理有限公司职工杨勇介绍，在天池南坡，这几年也曾经几次发现怪兽，并拍下过比较模糊的照片。

据记者了解，这是今年夏天长白山天池怪兽的第三次"现身"。8月3日，有游客在长白山北坡山顶发现了两只身体金黄、象鱼的"怪兽"，出现时间十几分钟。8月19日下午5点半左右，在难得一见的长白佛光出现半小时以后，几个旅游团的游客再次发展了两只黑乎乎的、体型很大、但不象一般的鱼的"怪兽"，持续时间约半小时。

长白山天池面积9．8平方公里，水面海拔2189米，平均水深204米，深达373米，是我国、深的火山口湖。

天池到底有没有“怪兽”？对此人们众说纷纭。一些严谨的自然科学工作者对此持否定态度，而百年来人们目睹的“不明游动物”又各有不同：有的说其头小、颈细、形体庞大，貌似恐龙；还有人说像小船、像水牛、像狗、像水獭

The Beijing Morning News reported on September 3, " 'monster'! Tianchi is a 'monster'! "September 2, the number of domestic tourists and more than 20 South Korean tourists treling to the southern slope of Changbai Mountains in Jilin Province, found swimming in the Tianchi in the few unknown biological.

Two hours before and after their trel to the south, imminent Tianchi shore, Dongpo shift to the direction of trel. From about 100 meters from the shore, the first three black spots disappear underwater. Plus, after three black spots before the three swam to the disappearance of black spots, where suddenly turned a large water droplets from a few black spots than this many times in the 10 large black spots, then these black spots disappear at the same time, there has been no further.

The southern slope of Changbai Mountain Scenic Spot Management Ltd. workers Yang Yong, in the southern slope of Tianchi, the past few years he also found several monsters, and took a more ambiguous picture.

According to report, this is Tianchi in Changbai Mountain monster this summer's third "visible."

UNITS OF THE INTERNATIONAL SYSTEM 制度的单位

kilogra千克mass质量kg

The International System (abbreviated SI, for Systeme International,

the French name for the system) was adopted in 1960 by the 11th

General Conference on Weights and Measures. An expanded and modified

version of the metric system, the International System addresses the

needs of modern science for additional and more accurate units of

decimalization, a system of prefixes, and a standard defined in

terms of an invariable physical measure.

制度（制度的缩写为SI，是制度的法语名称）被1960年的第十一届大会用于度量衡。公制的扩大和修改版本，即制度针对了现代科学附加的及更加正确的度量单位的需要。制度的主要特点是采用了十进制法、字首体系、以不变的物理度量方式解释的标准。

BASE UNITS 基本单位

The International System has base units from which all others in the

system are derived. The standards for the base units, except for the

kilogram, are defined by unchanging and reproducible physical

occurrences. For example, the meter is defined as the distance

treled by light in a vacuum in 1/299,792,458 of a second. The

standard for the kilogram is a platinum-iridium cylinder kept at the

International Bureau of Weights and Standards in Sevres, France.

制度有基本单位，由此衍生出此制度中的其他单位。除千克以外，基本单位的标准以不变的且可再生的物理为解释。例如，公尺被解释为光在真空中以每1/299,792,458秒的速度所穿越的距离。千克的标准是指置于法国塞夫勒的度量及标准局的白金铱圆柱为准。

单位数量符号

meter公尺length长度m

second秒time时间s

kelvin开temperature温度K

mole摩尔amount of matter数量mol

candela烛光luminous intensity发光强度cd

SUPPLEMENTARY UNITS 辅助单位

The International System uses two supplementary units that are based

on abstract geometrical concepts rather than physical standards.

制度采用了两种辅助单位，其依据于抽象的几何概念而非物理标准。

Radian弧度plane angles平面角rad

PREFIXES 字首

A multiple of a unit in the International System is formed by adding

a prefix to the name of that unit. The prefixes change the magnitude

of the unit by orders often from 10 18 to 10 -18.

经由在单位名称前面加一字首构成制度单位的倍数。字首通常按顺序从10的18次幂到10的-18次幂改变单位的量。
