This clip explains that the United States stands virtually alone in using the U.S. Customary System of Measurement (also known as the English System). Most of the world uses the Metric System. The clip lays out the Metric System equivalences for the...
Length: Converting Between the U.S. Customary and Metric Systems
This clip explains how to use both the unit cancellation and decimal methods to convert between the U.S. Customary and Metric Systems. "To convert between the two systems," the clip states, "we'll use a new equivalence: 1 inch equals 2.54 centimeter...
Compound Denominate Numbers: Compound Units
This clip presents several practical problems involving compound units. The problems include calculating a car's speed in miles per minute; the number of gallons of gas used; the force per square foot exerted by a waterbed; and the speed of sound ex...
Length: Units of Length in the Metric System
This clip lists some of the things metric units are used to measure, as well as the closest equivalent units in the U.S. Customary System.
Perimeter: Perimeter and Irregular Polygons
This clip explains that, "
we can find the perimeter of any polygon by adding the lengths of all sides." The clip includes practical problems and examples which demonstrate how this is done.
Length: Converting Meters to Feet and Kilometers to Miles
This clip presents practical problems in which meters must be converted to feet, and kilometers must be converted to miles. In the first problem, the student must determine how many feet of telephone cord are on a 100-meter roll. "We'll use the deci...
Length: Converting Inches to Yards, Feet to Miles, and Miles to Inches
This clip presents a variety of unit conversion problems which the student is first asked to write in equation form. The student is then instructed to write out fractions using the appropriate equivalence in each case. After cancellation, the studen...
