Overview

Length is measured to find how long, wide, tall, deep, or broad something is. A metre scale and a measuring tape help measure larger and smaller lengths clearly. One metre is divided into 100 equal parts, and each part is 1 centimetre. Different lengths can be written in different forms, such as 120

Key Concepts

Length tells how long

Length tells how long, tall, wide, deep, or broad something is. These words are used in different situations, but all of them mean length measurement.

Metre is the standard unit

Metre is the standard unit for measuring larger lengths. It is written as m.

Centimetre is the standard unit

Centimetre is the standard unit for measuring small lengths. A standard metre scale is divided into 100 equal parts, and each part is 1 cm.

1 metre (m) = 100 centimetres

1 metre (m) = 100 centimetres (cm). This means 100 cm together make 1 m.

A measuring tape has small marks

A measuring tape has small marks. The distance between two marks is 1 cm. The red bar is repeated 10 times to make 10 cm, and 100 such 1 cm parts make

Learning Objectives

  • Understand that height, width, depth, and breadth are all kinds of length.

  • Convert between metres and centimetres using 1 metre (m) = 100 centimetres (cm).
  • Measure small things with centimetres and larger things with metres.
  • Recognise that different unit forms can show the same length.
