The imperial system does not have conversion factors that are multiples of 10. Also, parts of imperial units are often expressed as fractions instead of decimals. The following table lists some common imperial conversion ratios.

 
Linear Possible Uses for the Larger Unit
12 inches = 1 foot length of a fence board, or height of a person

3 feet = 1 yard

36 inches = 1 yard

dimensions of a backyard, or length of a football field
1760 yards = 1 mile distance between two towns, or distance run in a marathon
Mass  
16 ounces = 1 pound weight of a person, a baby, some food, or an object
2000 pounds = 1 ton weight of a vehicle, dirt and gravel, or construction material
Capacity  
2 cups = 1 pint roughly the amount of beverage served in a large glass
2 pints = 1 quart a carton of ice cream
4 quarts = 1 gallon fuel (gasoline) and oil

 

Before continuing with the lesson, attempt to convert 4 pounds to ounces using the table.
