 * __ THE CUSTOMARY SYSTEM OF MEASUREMENT __**

The __**customary system**__ of measurment is used in the U.S. The attributes measured by the customary system are weight, length, and capacity. You can convert one unit of measure to another using the equivalencies given in the examples below. **__Weight__** The units to measure weight are the ounce, pound, and ton.

16 ounces (oz) = 1 pound (lb) example: a box of candy weighs a pound



2,000 pounds (lb) = 1 ton (T) example: a bull weighs about a ton

The units to measure length are, from smallest to largest, the inch, foot, yard, and mile.
 * __ Length __**

example: a quarter is an inch across



12 inches (in) = 1 foot (ft) example: a ruler is 12 inches or 1 foot long

36 inches (in.) = 3 feet (ft) = 1 yard (yd) example: doorknobs are a yard from the floor



5,280 feet (ft) = 1,760 yards (yd) =1 mile (mi) example: 4 times around the A field track is one mile



__**Capacity**__ The units to measure capacity are the fluid ounces, cup, pint, quart, and gallon. You can convert one unit of measure to another using the equivalencies below.

8 fluid ounces (fl oz) = 1 cup (c) example: a cup of coffee is 8 ounces

2 cups (c) = 1 pint (pt) example: a mug of root beer is a pint

2 pints (pt) = 1 quart (qt) example: a mason jar holds a quart

4 quarts (qt) = 1 gallon (gal) example: milk comes in gallon jugs




 * __ THE METRIC SYSTEM OF MEASUREMENT __**

The __**metric system**__ of measurment is used in the U.S. The attributes measured by the metric system are mass, length, and capacity. The metric system of measurement is based on 10 and powers of 10. The prefixes used for length, capacity, and mass tell what part of the basic unit is being considered. You can convert one unit of measure to another using the equivalencies given in the examples below.

hecto- deka- deci- centi- milli- || 1,000 100 10 0.1 0.01 0.001 || kilo- hecto- deka- deci- centi- milli- || k h da d c m || as in km for kilometers as in hm for hectometers as in dam for dekameters as in dm for decimeters as in cm for centimeters as in mm for millimeters || To change from one unit to another, multiply or divide by a power of 10.
 * kilo-

__** Mass **__ The metric system measures mass instead of weight. Mass is the amount of matter in an object and doesn't change. Weight is the pull of gravity on an object and changes depending how close you are to Earth.

1,000 milligrams (mg) = 1 gram (g) example: this weight is 1 gram

1,000 grams (g) = 1 kilogram (kg) example: this tiger cub is 1 kg

1,000 kilograms (kg) = 1 metric ton (t) example: 1000 water bottles are 1 metric ton

__** Length **__ 10 millimeters (mm) = 1 centimeter (cm) example: grid paper squares are one cm

1,000 millimeters (mm) = 10 decimeters (dm) = 1 meter (m) example: this fish stick is one meter

10 centimeters (cm) = 1 decimeter (dm) example: the length of a bar of soap = 1 dm

1,000 meters (m) = 1 kilometer (km) example: 100 school buses end to end = 1 kilometer




 * __ Capacity __**

1,000 milliliters (mL) = 10 deciliters (dL) = 1 liter (L) example: this water bottle is 1 liter
