Welcome to the third quiz in our Very Easy section of Eleven Plus maths all about measures. If you have played the previous two then you’ll have had some practice converting imperial measures to metric ones, and vice versa. In this quiz we’ll be mixing it up a bit, for example, do you know how many inches there are in a mile, or centimetres in a yard? Let’s find out!
Here are some facts you may need to know before we begin:
You may or may not need to know these for the quiz – but it’s always good to learn!
And now, on with the quiz. Good luck!















1.6 x 8 = 12.8 so there are 12.8 km in 8 miles
There are 1,000 metres in one km so there must be 12,800 metres in 8 miles: 12.8 x 1,000 = 12,800 

For this one, you need to know how many inches there are in one yard: 1 yard = 3 feet; 1 foot = 12 inches; one yard = 3 x 12 = 36 inches.
Now, 2.54 x 36 = 91.44 cm which we round down to 91 cm in one yard 
To work out the answer to this problem, we simply divide 100 by 0.62: 100 ÷ 0.62 = 161.29 which we round down to 161 km


17 ÷ 0.4 = 42.5 – it really is as easy as that!

You need to know how many pints are in one gallon to solve this one: 1 gallon = 8 pints.
Next, we simply divide 8 by 1.76: 8 ÷ 1.76 = 4.54 which we round down to 4.5 litres 

If 1 pint = 568 ml then it also equals 0.568 litres (because there are 1,000 ml in one litre: 568 ÷ 1,000 = 0.568).
Now all we have to do is times 0.568 by 2.25 to find the answer: 0.568 x 2.25 = 1.278 litres 
1,016 x 4 = 4,064. I hope that question wasn’t too easy!


There are 100 cm in one metre, so we need to divide 100 by 2.54 to find the answer: 100 ÷ 2.54 = 39.37 which we round down to 39 inches

Don’t let the speed rather than distance put you off – working out the answer is just the same: 80 x 1.6 = 128 kph

There are 1,000 metres in one kilometre so there must be 39,000 inches in one kilometre: 39 x 1,000 = 39,000
