In third grade measurement of mass we are going to focus on about what

is mass, customary unit of mass or weight and so forth,. The usual unit of weight or mass is gram and kilogram is the larger unit of weight. We write as ‘g’ and kilogram as ‘kg’. Kilogram is used to measure the heavier objects like a watermelon, faculty bag whereas gram is used to measure lighter objects like a chocolate, a tennis ball and so forth.

What

is mass?

The amount of matter in an object is named its mass. We

should know that the that means of mass of a physique is completely different from that of the

weight of that physique. The 2 phrases, mass and weight, are completely different in the true

sense. However within the preliminary phases for kids, the distinction is ignored and we

use the phrases weight and mass in the identical sense. Weight of an object modifications

from place to put, above and beneath the floor of the earth, however mass of a

physique by no means modifications. We all know, within the floor of the earth we take the items of

mass much like the items of weight.

Normal

Unit of Mass or Weight:

Now we have learnt to check weights of two various things through the use of a stability. We discover that, evaluating weight of a watermelon with bananas is just not the identical when it’s in contrast with mangoes. We have to use customary measures to search out the load or mass of any object. We use Grams and Kilograms to learn the way heavy issues are.

The usual unit of mass is kilogram and in brief it’s

written as kg. It’s used to measure the mass of heavy objects equivalent to baggage of

grain, stones, and so forth. The smaller unit of mass is gram and in brief it’s written

as g. It’s used to measure the mass of lighter objects.

We all know, 1000 g = 1 kg or 1 kg = 1000 g

In a grocery store we are able to see completely different weights to weigh various things.

Now, observe the next footage. The shopkeeper is weighing greens in kilograms and grams and the lady is measuring her weight in kilograms.

The usual weights or blocks are utilized by a shopkeeper to weight completely different objects with the assistance of a standard stability.

The usual unit of mass is the gram. The brief type for gram is g. We use grams to weigh lighter issues.

1000 grams makes one kilogram. We write kilogram as kg. We use kilograms to weigh heavier issues.

There are numerous kinds of stability scale obtainable now a days to measure weights of various objects. A few of these scales have digital show to indicate the load of an object.

To measure the load of a given object, we place the article on one pan of the stability and weights are positioned on the opposite pan.

When two objects weigh the identical, the 2 pans of the stability keep on the identical stage.

**Evaluation:**

**1.** The amount of matter in an object is name mass or weight.

**2.** Kilogram is beneficial for weighing heavy objects.

The signal of kilogram is ‘kg’.

**3.** Gram is beneficial for weighing lighter objects.

The signal of gram is ‘g’.

1000 g = 1 kg

**4.** To vary kg into g, multiply it by 1000 or put 3 zeros on the suitable.

Now, change 2 kg into g

2 kg = 2 × 1000 g = 2000 g

**5. **To vary kg and g into g, change the kg tog after which add the g.

Change 7 kg 476 g intog;

7 kg + 476 g

= 7000 g + 476 g 7 kg = 7 × 1000 g = 7000 g

= 7476 g

**6.** To changeg into kg and g. Divide the variety of g by 1000.

Quotient in it’s kg, the rest in it’s g.

Now, change 8796 g into kg and g

8796 ÷ 1000 = Quotient 8 and the rest 796

So, = 8 kg 796g
