Starry, you know that gram is the standard unit of measuring weights.

Look at these weights in grams.

This is a 10g weight, is a 20g weight.this is a 50g weight. this is a 100g weight.

this is a 200g weight, this is a 500g weight, and look at this.

Now, Starry, here is really big weight, it is the kilogram, this is a 1 kg weight.

All this weight are use to measures the weight of groceries, fruits, vegetables ,etc.

Let’s weight this bag of rice. Umm!         

When we place 250 gram weight on the other bag. The bag get balance.

Now 500 + 500 = 1000 gram. So this rice bag weight 1000 g.

Oh Starry! So you want to use a 1 kilogram weight to weight the rice  bag.

Ok, let’s do with them. 

Look Starry! This rice bag weight  1kg.

Hey Starry! You know what’s it mean?

Right! It’s mean 1000 gram as same as 1 kg.
So we can say that 1kg   =   1000 gram.

We can write a kilogram as “ kg” in short.

Now, let’s learn how to convert kilogram to gram.

Let’s convert 4 kg into grams.

Now 1kg = 1000g

So, 4kg = 1000 x 4 which equal 4000

So, 4kg = 4000g.

Easy! isn't it, Starry?

Let’s try another one. Let’s convert 7kg to grams.

Now 1kg = 1000g.

So 7kg = 1000 x 7 which equal 7000

So 7kg = 7000g

Now let’s provide how to convert kilograms to grams.

Convert 2kg to gram

1 kg = 1000g

So 2kg = 1000 x 2 which equal 2000g

So 2kg = 2000g

Now convert 5kg into grams

1kg = 1000g

so 5 kg= 1000 x 5 which equal 5000

So 5 kg = 5000g

Good! is it that  fun when different objects with standard units?
I’m sure it is!
