Perkaitan Kilometer dengan Meter
Kak Rina memandu di jalan kampung. Tiang lampu dipasang setiap 100 m. Dia melepasi 10 ruang antara tiang. Berapa kilometer dia sudah memandu?

千米和米的关系 = perkaitan km dengan m
千米和米都是量距离的单位。一千个一米连起来,就是一千米,所以 1 km = 1 000 m。知道这个关系,就能把千米换成米,也能把米换成千米。
例子:跑道一圈 400 m,五圈是 2 000 m,也就是 2 km。
注意:千米和米之间是一千倍,不是十倍或一百倍。
kilometres and metres = perkaitan km dengan m
Kilometres and metres both measure distance. One thousand metres joined together make one kilometre, so 1 km = 1 000 m. With this link you can change kilometres into metres and metres into kilometres.
Example: a 400 m track run five times is 2 000 m, which is 2 km.
Watch out: a kilometre is a thousand times a metre, not ten or a hundred times.
Perkaitan
1 km = 1 000 m
10 ruang × 100 m
setiap ruang = 100 m
10 × 100 m = 1 000 m = 1 km
1 千米等于 1 000 米 = 1 km sama dengan 1 000 m
每两根灯柱之间是 100 m,一共经过 10 段,就是 10 乘 100,等于 1 000 m。1 000 m 刚好是 1 km,所以丽娜姐开了 1 km。
例子:每段 500 m,两段也是 1 000 m。
注意:1 km 有三个零的米数,写的时候千位后面空一格。
1 kilometre is 1 000 metres = 1 km sama dengan 1 000 m
Each space between two lamp posts is 100 m. Ten spaces make 10 × 100 = 1 000 m, which is exactly 1 km, so Kak Rina has driven 1 km.
Example: two spaces of 500 m also make 1 000 m.
Watch out: 1 km in metres has three zeros; leave a space after the thousands digit.
km → m
Darab dengan 1 000
7 km = ? m
km —— × 1 000 ——▶ m
km ◀—— ÷ 1 000 —— m
km ◀—— ÷ 1 000 —— m
7 km = 7 × 1 000 m = 7 000 m
千米换米 = tukar km kepada m
大单位换小单位,数字变大。每 1 千米是 1 000 米,所以千米数乘 1 000,也就是在后面加三个零。七千米乘一千,得到 7 000 m。
例子:13 km = 13 × 1 000 = 13 000 m。
注意:乘 1 000 要加三个零,不是一个零。
kilometres to metres = tukar km kepada m
A bigger unit into a smaller one makes the number bigger. Each kilometre is 1 000 metres, so multiply the kilometres by 1 000, which adds three zeros. Seven kilometres is 7 × 1 000 = 7 000 m.
Example: 13 km = 13 × 1 000 = 13 000 m.
Watch out: multiplying by 1 000 adds three zeros, not one.
m → km
Bahagi dengan 1 000
15 000 m = ? km
km —— × 1 000 ——▶ m
km ◀—— ÷ 1 000 —— m
km ◀—— ÷ 1 000 —— m
15 000 m = 15 000 ÷ 1 000 km = 15 km
米换千米 = tukar m kepada km
小单位换大单位,数字变小。每 1 000 米合成 1 千米,所以米数除以 1 000,也就是去掉末尾三个零。一万五千除以一千等于十五。
例子:6 000 m = 6 000 ÷ 1 000 = 6 km。
注意:只有末尾三个都是零,才能直接去掉零。
metres to kilometres = tukar m kepada km
A smaller unit into a bigger one makes the number smaller. Every 1 000 metres make 1 kilometre, so divide the metres by 1 000, which removes three zeros from the end. Fifteen thousand divided by one thousand is fifteen.
Example: 6 000 m = 6 000 ÷ 1 000 = 6 km.
Watch out: you can only drop zeros like this when the last three digits are all zero.
km dan m → m
Tukar km, kemudian tambah m
3 km 58 m = ? m
3 km 58 m
= 3 000 m + 58 m
= 3 058 m
= 3 000 m + 58 m
= 3 058 m
千米米化成米 = tukar km dan m kepada m
先把千米部分乘 1 000 换成米,再加上米的部分。三千米是 3 000 m,加 58 m,得 3 058 m。米的部分只有两位数,所以百位要补一个 0。
例子:9 km 7 m = 9 000 m + 7 m = 9 007 m。
注意:千位后面一定有三位数字,不够就补零。
km and m into metres = tukar km dan m kepada m
Change the kilometre part into metres by multiplying by 1 000, then add the metres. Three kilometres is 3 000 m; adding 58 m gives 3 058 m. The metre part has only two digits, so a zero fills the hundreds place.
Example: 9 km 7 m = 9 000 m + 7 m = 9 007 m.
Watch out: there must be three digits after the thousands; fill with zeros if needed.
m → km dan m
Tiga digit terakhir ialah m
12 604 m = ? km ? m
米化成千米米 = tukar m kepada km dan m
看米数的最后三位数字:它们是剩下的米;前面的数字就是千米。一万二千六百零四米,最后三位是 604,前面是 12,所以是 12 km 604 m。
例子:27 350 m = 27 000 m + 350 m = 27 km 350 m。
注意:米的部分一定小于 1 000。
metres into km and m = tukar m kepada km dan m
Look at the last three digits of the metres: they are the metres left over, and the digits in front are the kilometres. In 12 604 m the last three digits are 604 and the front is 12, so it is 12 km 604 m.
Example: 27 350 m = 27 000 m + 350 m = 27 km 350 m.
Watch out: the metre part is always less than 1 000.
Semak cepat
9 km = ? m
千米换米 = tukar km kepada m
把千米换成米,是大单位换小单位,数字变大。每一千米有一千米的米数,所以乘 1 000:在后面加三个零。加好以后数一数零的个数。
例子:4 km = 4 × 1 000 = 4 000 m。
注意:乘 100 或乘 10 都不对,零的个数要数清楚。
kilometres to metres = tukar km kepada m
Changing kilometres into metres goes from a bigger unit to a smaller one, so the number grows. Multiply by 1 000, which adds three zeros, then count the zeros to check.
Example: 4 km = 4 × 1 000 = 4 000 m.
Watch out: multiplying by 100 or 10 is wrong; count the zeros carefully.

7 030 m = ?
米化成千米米 = tukar m kepada km dan m
米数的最后三位,一定是剩下的米(包括前面的零);最后三位前面的数字才是千米。先数出最后三位,再读前面的数。
例子:3 012 m 的最后三位是 012,前面是 3,因此写成 3 km 12 m。
注意:不要把中间的零算到千米那边去。
metres into km and m = tukar m kepada km dan m
The last three digits of the metres are always the metres left over, zeros included; only the digits in front of them are kilometres. Count off the last three digits first, then read the front.
Example: in 3 012 m the last three digits are 012 and the front is 3, so it is 3 km 12 m.
Watch out: do not move the middle zeros over to the kilometres.
Padankan
Padankan jarak yang sama
配对相同距离 = padankan jarak yang sama
左右两边的写法不同。把每个距离都换成米再比较最方便:千米乘 1 000,再加上米的部分。数字一样的两个距离就是一对。
例子:1 km 5 m 换成 1 005 m,所以它和 1 005 m 是一对。
注意:米的部分只有两位数时,要补零再比较。
matching equal distances = padankan jarak yang sama
The two sides are written differently. It is easiest to change every distance into metres: multiply the kilometres by 1 000 and add the metres. Two distances with the same number form a pair.
Example: 1 km 5 m becomes 1 005 m, so it pairs with 1 005 m.
Watch out: when the metre part has only two digits, fill in a zero before comparing.
Ringkasan
Syabas!
1 km = 1 000 m
km → m: darab 1 000. m → km: bahagi 1 000. Tiga digit terakhir ialah meter.
