1 Units of measure
A unit of measure is simply what you measure something in and you will already be familiar with using centimetres, metres, kilograms, grams, litres and millilitres for measurement. When measuring something, you need to choose the appropriate unit of measure for the item you are measuring. You would not, for example, measure the length of a room in millimetres. Have a go at the short activity below and choose the most appropriate unit for each example.
Activity _unit3.1.1 Activity 1: Choosing the unit
Using the following two lists, match each numbered item with the correct letter.
-

a.Weight of an egg
b.Weight of a dog
c.Amount of water in a paddling pool
d.Amount of liquid in a glass
e.Length of a garden fence
f.Length of a computer screen
- 1 = d
- 2 = e
- 3 = b
- 4 = a
- 5 = f
- 6 = c
Hopefully you found that activity fairly straightforward. Next you’ll take a closer look at some units of measure and how to convert between them.
