TermDefinitionExample Customary UnitsA system of measurement primarily used in the United States, including units like inches, feet, pounds, and gallons.When you measure your height in feet and inches, you are using customary units. Conversion FactorA ratio (fraction) that relates two different units of measurement, used to convert from one unit to another.The conversion factor between feet and inches is 1 foot = 12 inches, or $\frac{12 \text{ inches}}{1 \text{ foot}}$. LengthThe measurement of distance from one point to another.Common customary units of length are inches (in), feet (ft), yards (yd), and miles (mi). Weight (Mass)The measure of how heavy an object is, or the amount of matter it contains.Common customary units of weight are ounces (oz), pounds (lb), and tons (T). CapacityTh...

Converting Larger Units to Smaller Units To convert a measurement from a larger unit to a smaller unit, multiply the given value by the appropriate conversion factor. Use this rule when you want more of the smaller units to represent the same quantity. For example, converting feet to inches means you'll have more inches than feet. Converting Smaller Units to Larger Units To convert a measurement from a smaller unit to a larger unit, divide the given value by the appropriate conversion factor. Use this rule when you want fewer of the larger units to represent the same quantity. For example, converting ounces to pounds means you'll have fewer pounds than ounces. Proportional Conversion Method Set up a proportion where one ratio represents the known conversion f...
