Welcome to another Eleven Plus maths quiz on measures. This is the second of our medium level quizzes, and it will test how well you know your metric measurements.

There are several metric measurements in common usage. Take a look at this list:

- Length: millimetre (mm); centimetre (cm); metre (m); kilometre (km)
- Weight/mass: milligram (mg); gram (g); kilogram (kg); tonne
- Area: square millimetre (mm²); square centimetre (cm²); square metre (m²); hectare (ha)
- Volume: cubic millimetre (mm³); cubic centimetre (cm³); cubic metre (m³); millilitre (ml or mL); litre (l or L)

OK – now you know what we are dealing with, are you ready for the quiz? Take your time and read each question carefully.

1.

Which of the following lengths is the shortest: 1 km, 10,000 m, 1 million cm?

1 km

10,000 m

1 million cm

They are all the same

1 km = 1,000 metres, and 1 metre = 100 cm, so, 1 million cm is equal to 10 km

2.

What is 30.48 cm the same as?

1 mile

1 inch

1 foot

1 yard

You may have heard that there are 30 cm in 1 foot. This is an approximatuion. There are actually 30.48 cm in a foot

3.

How many grams are there in a tonne?

1,000

1 million

100,000

10,000

1 tonne = 1,000 kg, and 1 kg = 1,000 g. So, to convert tonnnes to grams, multiply by (1,000 x 1,000) = 1,000,000

4.

Which one of the following statements is false?

There are 1,000 millilitres in 1 litre

There are 1,000 metres in 1 kilometre

There are 1,000 grams in 1 kilogram

There are 1,000 millimetres in 1 centimetre

Of course there are 1,000 millimetres in 1 metre, not in 1 centimetre!

Kilo means 1,000 of something, while milli means^{1}⁄_{1,000} of something

Kilo means 1,000 of something, while milli means

5.

How many kilometres is 500,350 metres?

500.35 km

50.035 km

5.0035 km

5,003.5 km

1 km = 1,000 m, so to convert metres to km, just divide by 1,000: 500,350 ÷ 1,000 = 500.35

6.

A jug contains 1.756 litres of water. How much must be added to increase the amount to 2 litres?

2.44 ml

2,440 ml

24.4 ml

244 ml

1 litre = 1,000 ml, so 2 litres = 2,000 ml. 2,000 - 1,756 = 244

7.

How many cubic centimetres are there in 1 millilitre?

0.1

1

10

100

As well as being one-thousandth of a litre, a millilitre is also the same size as 1 cubic centimetre

8.

Which of the following has the least volume: 1,000 million mm³, 1 million cm³, 1 m³?

1,000 million mm³

1 million cm³

1 mm³

They are all the same

There are 1 million cm³ in 1 m³, and 1,000 mm³ in 1 cm³, so there are 1,000 x 1,000,000 mm³ in 1 m³

9.

How many kilograms are there in 1,000,000 (one million) grams?

100,000 kg

100 kg

10,000 kg

1,000 kg

1 kg = 1,000 g, so to convert grams to kg, just divide by 1,000: 1,000,000 ÷ 1,000 = 1,000

10.

Sophie weighs 6 stone. If 1 stone = 14 pounds and 1 pound = 0.45 kg, how many kg does Sophie weigh?

186 kg

64 kg

37.8 kg

34.6 kg

First, work out Sophie's weight in pounds: 6 x 14 = 84.

Next, convert pounds into kg by multiplying by 0.45: 84 x 0.45 = 37.8

Next, convert pounds into kg by multiplying by 0.45: 84 x 0.45 = 37.8
