Kilograms and Grams

What are kilogram and gram?

Kilogram (kg) and gram (g) are units of mass.

1 kg  =  1000 g
Or,
1000 g  =  1 kg

1. The mass of a fish is 1 kg 578 g.
What is the mass of the fish in grams?

We know,
1 kg  =  1000 g

Hence,
1 kg 578 g
=  1 kg  +  578 g
=  1000 g  +  578 g
=  1578 g

The mass of the fish is 1578 g.

2. Mrs. Mehra used 5 kg 10 g of soil for her garden.
Express the mass of soil she used in grams.

We know,
1 kg  =  1000 g

So,
5 kg  =  5000 g

Hence,
5 kg 10 g
=  5 kg  +  10 g
=  5000 g  +  10 g
=  5010 g

She used 5010 g of soil.

3. A bag has a mass of 7294 g.
What is its mass in kilograms and grams?

We know,
1000 g  = 1 kg

So,
7000 g  =  7 kg

Hence,
7294 g
=  7000 g  +  294 g
=  7 kg  +  294 g
=  7 kg 294 g

The mass of the bag is 7 kg 249 g.
