Convert a Range of Measures Including up to Three Decimal Places

In this activity, we're going to be converting a range of measures.  This may include using up to 3 decimal places.

 

Things we need to know - it is good to learn this information so that you can recall it when needed.

 

10 mm = 1 cm

100 cm = 1 m

1,000 m = 1 km

1,000 g = 1 kg

1,000 ml = 1 l

 

60 seconds = 1 minute

60 minutes = 1 hour

24 hours = 1 day

7 days = 1 week

356 days = 1 year (there are actually 365¼ days in a year) 

 

You might want to remind yourself of how we multiply and divide by multiples of 10  - all digits shift left or right and the decimal point never moves!

 

 

Let's have a look at an example of the type of question you might be asked:

 

Fred has a litre of juice.  He drinks 260 ml.

How much juice is left - give your answer in litres.

 

Answer

1 l = 1,000 ml

1,000 - 260 = 740 ml

740 ml = 0.74 l

0.74 litres remain.

 

Now it's your turn.
