In middle school Math as children advance, their knowledge of measures will increase. By now they should be very familiar with the metric measures (millimeters, centimeters, meters, kilometers, grams, kilograms, milliliters and liters) and should be comfortable combining measures to write measurements (eg. 1.5kg = 1kg 500g) and rounding smaller measurements up or down into larger ones (eg. 740m to 1km).

Grams and kilograms are used to measure the mass or weight of things. We can write the same weight in kg (1.6kg), in g (1,600g) or by combining the two (1kg 600g). Rounding fractions of larger measures to the nearest whole number is another way of writing measurements. 1.6kg would be rounded up to 2kg. Metric and imperial measurements are used all the time in day to day life. To know your grams from your ounces and your meters from your miles will stand you in good stead, so keep practicing these quizzes on measures.

How are you at combining m with km or rounding ml to the nearest l? Do you know your metric measures from your imperial ones? See how well you do in this quiz on measures.

2. Which of these statements is true?
[ ] 1 mile > 2 km
[ ] 1 mile < 1.5 km
[x] 1 mile > 1.5 km
[ ] 1 mile = 1.5 km

3. What is three quarters of 1 meter in cm?
[ ] 0.75cm
[x] 75cm
[ ] 750cm
[ ] 7,500cm
Three quarters of 100 is 75
4. How many grams are equivalent to one hundredth of a kg?
[ ] 0.1g
[ ] 1g
[ ] 1.1g
[x] 10g
There are 1,000g in a kg so 1,000 ÷ 100 = 10
5. What is 6.45kg expressed in grams?
[ ] 0.645g
[ ] 64.5g
[ ] 645g
[x] 6,450g
To convert kilograms to grams, times by 1,000
6. How do we write 4,520ml in liters?
[ ] 0.452 l
[x] 4.52 l
[ ] 45.2 l
[ ] 452 l
