This is the second of our Eleven Plus maths quizzes on measures and, like the first, it is very easy. In the previous quiz we looked in particular at metric measures, like metres, grams and tonnes. In this quiz we’ll also be investigating some old-fashioned imperial measures, like miles, inches, feet and yards.
Here are some comparisons to help you visualise:
Don’t worry if imperial measures seem a bit troubling. Play this quiz until you can score ten-out-of-ten, then you’ll be top of the class by a country mile!

There are 12 inches in 1 foot. You may have heard of someone being 5 feet 11 inches tall, but never 5 feet 12 inches tall: that would be 6 feet
|
There are three feet in a yard. If someone is 6 feet tall, they are also two yards tall

A mile was originally 1,000 paces. Of course, people have different leg lengths, so this was standardised to 1,760 yards under the reign of Henry VIII
|
When the metric system was introduced, the 'are' was 100 square metres. A hectare was 100 'ares', (hecto means 100, just as kilo means 1,000), 100 x 100 = 10,000 m²

Some imperial meaures, like the foot for example, are based on body parts. Others are based on seemingly random things, like the size of barley grains, the distance travelled in an hour or the amount of land an ox can plough in a day!

There are 3 feet in a yard and 12 inches in a foot: 12 x 3 = 36

There are 1,760 yards in a mile and 3 feet in a yard: 1,760 x 3 = 5,280
|
There are 12 inches in 1 foot, so there must be 24 inches in 2 feet. 24 x 2.54 = 60.96.
You may have heard that there are 30 cm in 1 foot but this is an approximation. There are actually 30.48 cm in 1 foot |

To convert miles to km (approximately) multiply the number of miles by 1.6: 10 x 1.6 = 16
|
Again, this is an approximation. There are actually 39.3701 inches in 1 metre - converting imperial to metric (and vice versa) is not so simple!
