Learn Class 5 Math - Weight

Have you analysed why your lunch box weight is heavier or lighter than in previous days? Have you ever felt that your school bag is heavier than your classmate's bag? This heaviness of the object is called weight. It is the most important chapter of mathematics that every class 5 student should know. Let us have a detailed discussion regarding this topic.

The weight of the object measures the heaviness and lightness of the object. Kilograms and grams are used to express the exact weight of the object. However, you can determine the accurate weight of the object through several other units.

What to do if you wish to determine the exact weight of the lighter object? In such a situation, grams are an ideal unit to determine the weight lighter object. Gram is one of the lighter units. Some of the examples of these units are as follows.

  • A kilogram is denoted as 'kg'
  • Gram is denoted as 'gm'
  • 1 kilogram = 1000 gm
  • 1 gm = 1000mg (milligram)

Calculate weight using a weighing scale

For determining the weight of the object, you can also use the weighing scale. Let's understand with the help of an example.

If you want to determine the weight of the pineapple through the weighing scale, Take the weighing scale and keep the object on the one side of the pan and the object whose weight needs to be measured on the other side of the pan. For example, take the object that weighs 1 kg and keep it on one side of the pan and pineapple on the other side. If the weight of both the pan shows equal, then it means that the weight of pineapple is 1 Kg.
