The english system of measurement
1. The English System of MeasurementTopic IndexĀ |Ā Algebra IndexĀ |Ā Regents Exam Prep CenterĀ The English system of measurementgrew out of the creative way that people measured for themselves.Ā Familiar objects and parts of the body were used as measuring devices.Ā For example, people measured shorter distances on the ground with their feet.Ā They measured longer distances by their paces (a quot;
milequot;
was a thousand paces).Ā They measured capacities with common household items such as cups, pails, and baskets.Ā The wordgallonĀ comes from an old name for a pail.Ā Ā Unfortunately, these creative measuring devices allowed for different measurements to be obtained when different people measured the same items.Ā Eventually, a standard was set so that all measurements represented the same amount for everyone.Ā Ā Length:12 inches (in) = 1 foot (ft)3 feetĀ = 1 yard (yd)Ā 5280 feet = 1 mile (mi)Ā Capacity:3 teaspoons (tsp) = 1 tablespoon (tbsp)Ā 16 tbsp = 1 cup (c)8 ounces (oz) = 1 c2 c = 1 pint (pt)2 pt = 1 quart (qt)4 qt = 1 gallon (gal)Weight:16 ounces (oz) = 1 pound (lb)2000 lb = 1 tonĀ Ā ConversionsSometimes you need to convert from one unit of measure to another similar unit.Ā How many inches are in 3 feet?Ā How many ounces in 5 pounds?Ā Ā Proportions will help you make conversions when working with measurements.Create a unitĀ conversion ratio, which is always equal to 1:Ā Ā Ā Ā Ā Ā Example 1:Ā Ā How many yards are in 15 feet?There are 3 feet in one yard, so theĀ conversion ratioĀ is 1 yd / 3 ft:Solving algebraically gives an answer ofĀ 5 yards.Ā Ā Ā Example 2:Ā Ā How many cups in one gallon?There is no direct connection from cups to gallons.Ā There are, however, 4 cups in one quart and 4 quarts in one gallon.Ā So theĀ conversion ratioĀ could be:Solving algebraically gives an answer ofĀ 16 cups.Ā <br />
