MWA 10 4.4 Conversions

1. Making Conversions
Slide 1
In this lesson, you will learn how to convert from a unit
of volume to a unit of weight.
For example, grain is often measured in bushels, a
volume measure, but its weight may be needed to
judge whether it is a safe load for a truck. Each gran
has a different weight, so conversions between
bushels and weight depend on knowing the
conversion factor.

2. Slide 2
Example 1:
How many bushels (bu) of flax seed are there in 2.4 tonnes, if
the conversion factor is 39.368 bushels/tonne?

3. = 2.4 tonnes x 39.368 bushes/tonne
= 94.5 bushels
Slide 3
Example 1:
How many bushels (bu) of flax seed are there in 2.4 tonnes, if
the conversion factor is 39.368 bushels/tonne?
Answer:
There are approximately 94.5 bushels of flax
seed.

4. Slide 4
Example 2:
Alphonse is making chicken kebabs for 14 people. His recipe
suggests about 7 oz of chicken per person. At the grocery
store, the weight of the chicken is labelled in kilograms. How
much chicken does Alphonse need to buy?

5. Calculate amount of ounces needed
14 people x 7 oz
= 98 oz
Convert to kilograms
= 98 oz x 28.3495 g/oz
= 2778.251 grams
= 2.78 kilograms
