Measurement Length, Weight and Capacity

Category : 1st Class


This lesson will help you to:-

  • compare length, height, weight and capacity.
  • Measure length, height, weight and capacity.



Measurement is finding a number that shows the size or amount of something. We can measure many different things, but mostly we measure length, weight, capacity, time and mass. Here we will learn the measurement of length, weight and capacity.



  • A measurement of how long something is.
  • We can measure the length of an object using metre rod, tape or ruler.


Do You Know?

A grain of wheat was used to measure gold and silver in early days.


Real Life Example

Shopkeeper uses a weighing balance to measure the weight of fruits and vegetables.


Compare Length: Longer or Shorter


We use words ‘Longer’ and ‘Shorter’ to compare the length of things that are lying down.

We can compare the things that are longer and shorter by putting them next to each other.

Compare Height: Taller or Shorter

Height tells us how tall or short something is.

We use words ‘taller’ and ‘shorter’ to compare the height of things that are standing up

We can compare the height of different things by making them stand next to each other.



Historical Preview

In ancient times, there was no measuring system. People used to measure things with the help of body parts. For example: to measure the length of a cloth they used the handspans.


Standard Units

Standard units of measurement of

(a) Length:

Centimetre (for small lengths)

Metre (for big lengths)

(b) Capacity: Litre (for more capacity)

Millilitre (for less capacity)

(c) Weight: kg (for Heavy object) g (for light objects)



1. Using Another Object

We can measure the length of an object by using another object.

For Examples:


2. Using Body Parts:

We can measure the length of an object by using body parts. For example, you can use you hand to measure length of you study table.


Non- standard Units of Measuring Length




The words big and small tell us about the size of an object.

For examples:




The words thick and thin tell us about the thickness of an object.

For examples:



A measurement of how heavy something is. We use the words ?heavier? or ?lighter? to compare the weights of things.


  1. We can use a balance to compare heavier and lighter thing, the heavier side of the balance will go down.
  2. We can hold things to see if they are light or heavy



Capacity can be defined as the amount that any object can hold. For example, a bucked can hold 20 litres of water.

This means the capacity of the bucket is 20 litres.



We can compare the capacity of containers by pouring the water of any other liquid into small cups or mugs.



We can measure how much water a container can hold by seeing how many small cups of water it can fill.
