5 This week's quiz
Hopefully, the last activity has given you a feel for how the basic ideas that you have been building up and using in the last two weeks can be applied in any situation where you need to convert between different units. Always keep in mind the three steps that are needed:
- Find out how the two units are related to each other – the ‘conversion factor’.
- Ask yourself if the final answer should be bigger or smaller than the original value.
- Divide or multiply by the conversion factor to get your answer.
