Metres and Centimetres

What are metre (meter) and centimetre (centimeter)?

Metre (m) and centimetre (cm) are units of length.

1 m  =  100 cm
Or,
100 cm  =  1 m

1. A rope is 1 m 84 cm long.
Find the length of the rope in centimetres.

We know,
1 m  =  100 cm

Hence,
1 m 84 cm
=  1 m  +  84 cm
=  100 cm  +  84 cm
=  184 cm

The rope is 184 cm long.

2. What is 3 m 9 cm in centimetres?

We know,
1 m  =  100 cm

So,
3 m  =  300 cm

Hence,
3 m 9 cm
=  3 m  +  9 cm
=  300 cm  +  9 cm
309 cm

3. A ceiling is 882 cm high.
Express the height of the ceiling in metres and centimetres.

We know,
100 cm  =  1 m

So,
800 cm  =  8 m

Hence,
882 cm
=  800 cm  +  82 cm
=  8 m  +  82 cm
=  8 m 82 cm

The ceiling is 8 m 82 cm high.
