1 3 Name Linear Measurement: Imperial Uses of imperial measurement: Many North American sports use imperial units. For example, the CFL uses a football field that is 0 yards long. An NBA basketball hoop is 0 feet high. Most people know their height in feet and inches. Many lengths for wood needed in construction projects are given in feet and inches. For example, plywood boards are 4 feet by 8 feet.. What are other uses of imperial measurement?. Europe uses the metric system. The United States uses the imperial system. Which system should Canada use? Why? Chapter 3 Linear Measurement: Imperial MHR 67

3 Units of Imperial Measure The basic units of linear measure in the imperial system are the inch, the foot, the yard, and the mile. An imperial ruler is one foot long. There are... inches in foot. There are 3 feet in yard. So, there must be x 3 inches in yard. There are 760 yards in a mile. (You rarely would need to know this!!) How many feet would be in one mile? Write the four basic units of imperial measure in order from smallest to largest. It is important to become familiar with the common abbreviations for imperial units. What is meant by an abbreviation? You will need to know these: Yard Mile ftor' yd mi Most imperial rulers and measuring tapes divide an inch into 6 parts.
