Maths Quiz - Level 3-4 Shapes - Measuring Mass (Answers)
In your KS3 Maths lessons on shapes, you'll get to do some cool measurements! You're already familiar with measuring areas, distances (like width or length), and volumes or capacities. Now, let's talk about measuring weight or mass.
Technically, 'weight' and 'mass' have differences, but for everyday use, they're pretty much the same. In maths, we measure both in grams (g), kilograms (kg), and tonnes. Easy tip: 1,000 grams make a kilogram, and 1,000 kilograms make a tonne.

Converting between metric measurements of mass is simple - just divide or multiply by 1,000. There are more complicated imperial units like ounces, pounds, stones or tons, but we'll look at these in a later quiz. This one sticks to metric weights.
Test your knowledge of measuring mass metrically in the quiz below. Have fun!

Multiply 4.5 x 1,000 for the answer
|
500kg = 0.5 tonnes so 10 - 0.5 - 2.5 = 7 tonnes

Half a kilo = 500 grams. The abbreviation g = grams
|
666g ÷ 31⁄3 = 199.8 which we can round up to 200. So, 200 coins each worth 1p means that Peter's collection is worth £2.00

Don't forget that k = kilo and g = gram
|
Make sure that you understand that a kilo is 1,000 grams and that 400 grams is 0.4 of a kilo
