標題: [問題] ml毫升=c.c.立方公分嗎?
時間: Tue Apr 12 13:26:11 2011
我在某化妝品保養網站
因為看到自填選項的下拉選單有ml與c.c.兩個選項
於是寫了留言道
容量的單位 〔ml〕〔c.c.〕這兩個意思是一樣的
1ml=1毫升=1cc=1公撮=千分之一公升
之後P網友回應如下
說明:
●ml是英文名milliter的縮寫。
●c.c.是英文名cubic centimetes的縮寫。在標準情況下,1毫升水的容量
極接近於1立方厘米(俗稱c.c.)的積體,但並不完全相符,c.c.和毫升在
表面上看來似乎是等量的單位,嚴格說則不然,c.c.是體積,毫升是容量,
例如:奶粉的一匙量就是用c.c.來計算
-------------------------------------------------
對方應該是參考這裡http://0rz.tw/K4t83
因為單字拼錯的地方是一樣的
不過我想問centimetre或centimeter需不需要加s呢?
and 公撮=ml嗎? 還是公撮=c.c.
之後我再估狗 目前查到的是
「一公尺等於光在真空中於 1/299,792,458 時間間隔內所行經之距離」
「一立方公尺等於每邊長為 一公尺 之正方體體積」
http://0rz.tw/DSDmn
以下是我自己寫的 有錯請指正
1 cm(centimeter)=1/100 m(meter)
1 c.c.(cubic centimeter)=1/1000000 m^3(cubic meter)
就我估狗查到公升的定義
A litre is defined as a special name for a cubic decimetre
http://0rz.tw/peoXb
A decimetre is a unit of length in the metric system,
equal to one tenth of a metre, the current SI base unit of length.
In simple words there are 10 cm in a decimetre.
http://0rz.tw/ycfRx
以下是我自己寫的 有錯請指正
1 ml(milliliter)=1/1000 L(liter)
1 ml = 1/1000 L = 1/1000 dm^3 = 1/1000000 m^3 = 1 cm^3 = 1 c.c
以上我不知道哪裡有瑕疵
或許關鍵是在decimeter的定義
P網友的意思我大概可以瞭解
但能否請諸位行家 修正我們的錯誤
我滿想知道正確的解釋該是如何 謝謝^^

如果我這樣解釋會不會比較好呢? 再請大家指正錯誤
mL與c.c. 都是unit of volume
volume是物理量
P網友所說的容量與體積是中文詞意
不應從中文詞意去扭曲解釋一個物理量
所以並沒有所謂體積的單位.容量的單位那種東西
以下原文引自Chemistry sixth edition 第9.10頁
作者為Steven S. Zumdahl 出版社為Houghton Mifflin Company
ISBN:0618265058
[One physical quantity that is very important in chemistry is volume, which
is not a fundamental SI unit but is derived from length. A cube that measures
1 meter (m) on each edge is represented in Fig. 1.6. This cube has a volume
of (1 m)^3=1 m^3. Recognizing that there are 10 decimeters (dm) in a meter,
the volume of this cube is (1 m)^3=(10 dm)^3=1000 dm^3. A cubic decimeter,
that is (1 dm)^3, is commonly called a liter (L), which is a unit of volume
slightly larger than a quart. As shown in Fig. 1.6, 1000 liters are contained
in a cube with a volume of 1 cubic meter. Similarly, since 1 decimeter equals
10 centimeters (cm), the liter can be divided into 1000 cubes each with a
volume of 1 cubic centimeter:
1 liter = (1 dm)^3 = (10 cm)^3 = 1000 cm^3
Also, since a cm^3=1 milliliter (mL).
1 liter = 1000 cm^3 = 1000 mL
Thus 1 liter contains 1000 cubic centimeters, or 1000 milliliters.]
如此來說 我應該能很肯定的說mL等於c.c.了吧?
