Measurements

Length in metres and kilometers

For lengths, much greater than metres, we use kilometres.

Kilometre is used to measure distances from one place to another.

There are one thousand metres in one kilometer

1 km = 1000 m

'kilo' in 'kilometers' means one thousand or 1000.

The distance between Ali's house and his school is 1 km

We can also say that the distance is 1000 m

The distance between school and railway station is 5 km 200 m

Example : Let's convert this distance into metres

5 km 200 m = 5 km + 200m

= 5000 m + 200 m

= 5200 m

The distance between two towns is 7400 m. Can you convert this distance into kilometres and metres?

7 400 m = 7000 m + 400 m

= 7 km + 400 m

= 7 km 400 m
