FC: Measurement: Customary and Metric Systems

1: Customary System There are two basic systems of measurement. When measuring in these systems, a comparison is made to some unit recognized as a standard. The system used in the United States is called the customary system of measurement. | The units of measure in the customary system are: LENGTH 1 foot (ft) = 12 inches (in.) 1 yard (yd) = 3 feet 1 yard = 36 inches 1 mile = 1,760 yards 1 mile = 5,280 feet WEIGHT 1 pound (lb) = 16 ounces (oz) 1 ton (T) = 2,000 pounds CAPACITY 1 pint (pt) = 2 cups 1 quart (qt) = 2 pints 1 quart = 4 cups 1 gallon (gal) = 4 quarts

2: The other basic system of measurement is called the metric system, or SI (International System of Units). It was first adopted in France and is currently used by approximately 95% of the world's population. | Red- Customary Gray- Metric | Metric System

3: Relationships Between the Metric System and Customary System | Length: 1 in= 2.54 cm 1 mi= 1.6 km | Capacity: 1 qt= 0.95 L | Weight and Mass 1lb=0.45 kg | Using these relationships, we can convert back and forth between the Metric System and the Customary System.

4: Converting Units | Convert 5 liters to quarts. -We know that liters is a metric unit, and that quarts are a customary unit, so we are converting from metric to customary. We also know that 1qt= 0.95, so: 5L x 1qt/0.95L= 5.26qt Approximately 5L= 5.26qt Convert 3 miles to kilometers. -We know that miles is customary, and that kilometers are metric, so we are converting from customary to the metric system. We also know that 1mi= 1.6km, so: 3mi x 1.6km/ 1mi= 4.8km Approximately 3mi= 4.8km

5: Convert: 1. 7 mi= ___km 2. 12 qt= ___ L 3. 25 kg= ___ lb 4. 8 cm= ___ in. 5. 85 lb= ___ kg | Practice
