Worksheet Overview

In this activity, we're going to be converting between grams and kilograms, and millilitres and litres.

 

Information that will help us:

There are 1,000 g in one kg

There are 1,000 ml in one litre

g = gram

kg = kilogram

ml = millilitre

l = litre

 

When we multiply by 1,000, all the digits move three places to the left (the decimal point does not move)

When we divide by 1,000, all the digits move three places to the right (the decimal point does not move)

 

We can use the information above to help us answer the questions in this activity.

It is useful to learn this information and keep it in your head!

Let's have a look at an example:

 

How many g are there in 3 kg?

We know that there are 1,000 g in 1 kg

To convert 3 kg into g we need to multiply 3 by 1,000

3 x 1,000 = 3,000 

3 kg = 3,000 g

 

Now let's look at another question - this time as a word problem.

 

A  bottle holds 2 l of cola.

Billy drinks 200 ml of cola.

How many ml of cola are left?

 

cola bottle   

 

First ,we need to find the total amount in ml.

2 l = 2 x 1,000 = 2,000 ml

Now we subtract 200 ml

2,000 - 200 = 1,800 

There are 1,800 ml left in the bottle.

 

Now, why don't you have a go at some questions?
