Convert Between Different Units of Measure

In this activity, we're going to be converting between different units of measure.

 

Things we need to know:

There are 10 mm in a cm

There are 100 cm in 1 m

There are 1,000 m in 1 km

There are 1,000 ml in 1 l

There are 1,000 g in 1 kg

mm = millimetre

cm = centimetre

m = metre

km = kilometre 

g = gram

kg = kilogram

ml = millilitre

l = litre

 

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:

 

Convert 13,000 m into km.

We know that there are 1,000 m in 1 km.

To convert m to km we simply need to divide 13,000 by 1,000

13,000 ÷ 1,000 = 13 (all the digits move 3 places to the right)

 

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

 

Verity has a 2 l bottle of cola 

She drinks 3 glasses of the cola.  

Each glass holds 250 ml

How much cola is left in the bottle?

 

 

First, we need to convert the litres to millilitres.

2 l = 2,000 ml

Each glass holds 250 ml

3 x 250 ml = 750 ml

 

Finally, subtract 750 from 2,000

2,000 - 750 = 1,250 ml

 

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