Introduction to Measurement

What you need to know  First things first, you need to understand the basics  There are two systems of measurement  US/Customary (English) System which we use here  Then there is the metric system which is used all over the world

Measurement Basics  Length: a measured distance  Volume/Capacity: how much something can hold (generally liquid)  Weight: a measure of the heaviness of an object  Mass: the amount of matter in an object

US/Customary System  The English system has many different units of measurement  Each unit has a completely different name  They also have completely different conversion factors

Metric System  The metric system has a base 10 unit and many different prefixes  Do you remember any?

Metric Units of Measurement  Meters: Measures length  Liters: Measures volume or capacity  Grams: measures weight/mass

Units of Measurement: Volume  English System  Cups  Pints  Quarts  Gallons  Fluid Ounces  Metric System  Liters

Units of Measurement: Length  English System  Inches  Feet  Yards  Miles  Metric  Meters

Units of Measurement: Weight/Mass  US System  Ounce  Pound  Tons  Metric  Gram

Metric System Prefixes  Kilo= 1000  Hecto=100  Deka= 10  METERS/LITERS/GRAMS  Deci=1/10 or 0.1  Centi= 1/100 or 0.01  Mili=1/1000 or 0.001

US Conversions  Length  1 foot = 12 inches  1 yard = 3 feet  1 mile = 5,280 feet

US Conversions  Volume  1 cup = 8 fl oz  1 pint = 2 cups  1 quart = 2 pints  1 gallon = 4 quarts

US Conversions  Weight  1 lb = 16 oz  1 ton = 2000 lbs

Try this easy rule:   King   Henry   Died   Bravely (   Drinking   Chocolate   Milk Meter, Liter or Gram )

  K = kilo   H = hecto   Dk = deka   B = gram or meter or liter   D = deci   C = centi   M = milli
