Succeed with maths – Part 2

Week 1: Measurement of length

Introduction

Welcome to the first week of Succeed with maths – Part 2. The first two weeks of this course will focus on measurement and the units that are used to communicate this.

People use numbers to solve a wide variety of different problems, including when designing buildings, navigating and working out the fuel consumption of an aircraft. These examples all use measurements that involve distance and it is these types of situations this week will be concentrating on. For this, it is important that you have a working knowledge of various units of measurement and the two different measurement systems used in the UK – The Système Internationale (SI) or International System, on which the metric system is based, and imperial. Both of these will be covered over the next two weeks, and this week will look in particular at measuring length.

Transcript

Maria Townsend:
This is my height measured in books, not a common unit of measurement but still an interesting one. This does give us a problem though. If I measure myself again using other books I’ll get a different answer as they’re not all the same size.

So to use the book as a unit of measurement I’d always have to use the same book and tell everybody what that book was. And something similar is true for all measurements as you’ll find out this week.

After this week’s study, you should be able to:

  • understand how the International System (SI) is formulated
  • understand the more common SI units for length and convert between them
  • recognise the more common imperial units for length and convert between these
  • understand how the SI and imperial units of length relate to each other.
