Perkaitan Sentimeter dengan Milimeter

Mei Ling mengukur seekor anak ikan di akuarium. Pembaris menunjukkan 4 cm 6 mm. Kawannya berkata panjangnya 46 mm. Siapakah yang betul?

Perkaitan Sentimeter dengan Milimeter
厘米和毫米的关系 = perkaitan cm dengan mm 同一个长度可以用不同单位来写。1 厘米里面有 10 个 1 毫米,所以 1 cm = 10 mm。知道这个关系以后,就能把厘米换成毫米,也能把毫米换回厘米,看看两个写法是不是同一个长度。 例子:2 cm 3 mm 和 23 mm 是同一个长度。 注意:换单位以后,长度本身没有变,只是数字和单位变了。
centimetres and millimetres = perkaitan cm dengan mm The same length can be written with different units. One centimetre holds ten millimetres, so 1 cm = 10 mm. With this link you can change centimetres into millimetres and back, and see whether two ways of writing are the same length. Example: 2 cm 3 mm and 23 mm are the same length. Watch out: changing units does not change the length, only the number and the unit.

1 cm = 10 mm

1 cm = 10 mm
1 厘米等于 10 毫米 = 1 cm sama dengan 10 mm 看尺子:从 0 到 1 之间有 10 个小格,每一小格是 1 mm。所以 1 cm 刚好等于 10 mm。2 cm 就有 20 个小格,3 cm 就有 30 个小格。 例子:一枚硬币直径约 2 cm,也就是约 20 mm。 注意:厘米是大单位,毫米是小单位;同一个长度,用毫米写的数字比较大。
1 centimetre is 10 millimetres = 1 cm sama dengan 10 mm Look at the ruler: between 0 and 1 there are 10 small spaces, each 1 mm. So 1 cm is exactly 10 mm. Two centimetres hold 20 small spaces and three hold 30. Example: a coin about 2 cm across is about 20 mm across. Watch out: the centimetre is the bigger unit, so the same length has a bigger number in millimetres.

7 cm = ? mm

cm —— × 10 ——▶ mm
cm ◀—— ÷ 10 —— mm
7 cm = 7 × 10 mm = 70 mm
厘米换毫米 = tukar cm kepada mm 大单位换成小单位,数字会变大。每 1 厘米是 10 毫米,所以几厘米就乘 10。七厘米乘十等于七十毫米。 例子:13 cm = 13 × 10 = 130 mm。 注意:乘 10 就是在数字后面加一个 0,不是加 10。
centimetres to millimetres = tukar cm kepada mm Changing a bigger unit into a smaller one makes the number bigger. Each centimetre is 10 millimetres, so multiply the centimetres by 10. Seven centimetres times ten is seventy millimetres. Example: 13 cm = 13 × 10 = 130 mm. Watch out: multiplying by 10 puts a zero after the number; it is not adding 10.
mm → cm

90 mm = ? cm

cm —— × 10 ——▶ mm
cm ◀—— ÷ 10 —— mm
90 mm = 90 ÷ 10 cm = 9 cm
毫米换厘米 = tukar mm kepada cm 小单位换成大单位,数字会变小。每 10 毫米合成 1 厘米,所以毫米数除以 10。九十除以十等于九,九十毫米就是九厘米。 例子:170 mm = 170 ÷ 10 = 17 cm。 注意:除以 10 就是去掉末尾的一个 0。
millimetres to centimetres = tukar mm kepada cm Changing a smaller unit into a bigger one makes the number smaller. Every 10 millimetres make 1 centimetre, so divide the millimetres by 10. Ninety divided by ten is nine, so ninety millimetres is nine centimetres. Example: 170 mm = 170 ÷ 10 = 17 cm. Watch out: dividing by 10 removes one zero from the end.
cm dan mm → mm

Tukar cm, kemudian tambah mm

14 cm 6 mm = ? mm

14 cm 6 mm
= 140 mm + 6 mm
= 146 mm
厘米毫米化成毫米 = tukar cm dan mm kepada mm 长度有两部分:厘米部分和毫米部分。先把厘米部分乘 10 换成毫米,再加上原来的毫米部分。十四厘米是一百四十毫米,加六毫米,一共一百四十六毫米。 例子:9 cm 2 mm = 90 mm + 2 mm = 92 mm。 注意:毫米部分不用再乘 10,直接加上去。
centimetres and millimetres into millimetres = tukar cm dan mm kepada mm The length has two parts. Change the centimetre part into millimetres by multiplying by 10, then add the millimetre part. Fourteen centimetres is one hundred and forty millimetres; add six to get one hundred and forty-six millimetres. Example: 9 cm 2 mm = 90 mm + 2 mm = 92 mm. Watch out: the millimetre part is not multiplied; just add it.
mm → cm dan mm

= 250 mm + 7 mm
= 25 cm 7 mm
毫米化成厘米毫米 = tukar mm kepada cm dan mm 把毫米数拆成两部分:能被 10 整除的部分,和剩下的个位。整十的部分除以 10 变成厘米,个位留下来当毫米。二百五十七拆成二百五十和七,二百五十毫米是二十五厘米,剩七毫米。 例子:83 mm = 80 mm + 3 mm = 8 cm 3 mm。 注意:个位的数字就是剩下的毫米。
millimetres into centimetres and millimetres = tukar mm kepada cm dan mm Split the millimetres into two parts: the part that divides exactly by 10, and the ones left over. Divide the tens part by 10 to get centimetres; the ones stay as millimetres. Two hundred and fifty-seven splits into two hundred and fifty and seven: twenty-five centimetres and seven millimetres. Example: 83 mm = 80 mm + 3 mm = 8 cm 3 mm. Watch out: the ones digit gives the millimetres left over.

6 cm = ? mm

厘米换毫米 = tukar cm kepada mm 题目要把厘米换成毫米,是大单位换小单位,数字会变大。方法:厘米数乘 10。只乘一次 10,因为 1 厘米刚好是 10 毫米。 例子:3 cm = 3 × 10 = 30 mm。 注意:乘 100 是把米换成厘米时用的,不要混淆。
centimetres to millimetres = tukar cm kepada mm The question changes centimetres into millimetres, a bigger unit into a smaller one, so the number grows. Method: multiply the centimetres by 10, once only, because 1 cm is exactly 10 mm. Example: 3 cm = 3 × 10 = 30 mm. Watch out: multiplying by 100 is for metres to centimetres; do not mix them up.

312 mm = ? cm ? mm

毫米换厘米毫米 = tukar mm kepada cm dan mm 先把毫米数拆开:个位的数字留作毫米,其余的整十部分除以 10,变成厘米。毫米部分一定小于 10,因为满 10 毫米就是 1 厘米。 例子:248 mm = 240 mm + 8 mm = 24 cm 8 mm。 注意:毫米的部分不能是 10 或以上。
millimetres to cm and mm = tukar mm kepada cm dan mm Split the millimetres: the ones digit stays as millimetres, and the rest, a number of tens, is divided by 10 to give centimetres. The millimetre part must be less than 10, because 10 millimetres make a centimetre. Example: 248 mm = 240 mm + 8 mm = 24 cm 8 mm. Watch out: the millimetre part cannot be 10 or more.
Padankan

Padankan ukuran yang sama panjang

配对相同长度 = padankan ukuran yang sama 两边的写法不同,有的是厘米和毫米,有的只有毫米或只有厘米。最稳的方法是全部换成毫米再比较:厘米乘 10,加上毫米部分。换好以后,数字相同的就是一对。 例子:6 cm 4 mm 换成 64 mm,所以它和 64 mm 是一对。 注意:每个长度只能配一次。
matching equal lengths = padankan ukuran yang sama The two sides are written differently: some in centimetres and millimetres, some only in millimetres or only in centimetres. The safest way is to change everything into millimetres: multiply the centimetres by 10 and add the millimetres. Equal numbers make a pair. Example: 6 cm 4 mm becomes 64 mm, so it pairs with 64 mm. Watch out: each length is used in one pair only.
