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

3. Measurement Basics • Length: is the distance of something measured • Volume/Capacity: how much something can hold ( generally liquid) • Weight: how much something weighs • Mass: how much space something takes up

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

5. Metric System • The metric system has base unit and many different prefixes

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

7. US System Cups Pints Quarts Gallons Fluid Ounces Metric System Liters Units of Measurement:Volume

8. US System Inches Feet Yards Miles Metric Meters Units of Measurement:Length

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

10. Metric System Prefixes • Mili- 1/1000, which means that 1000mm=1m • Centi- 1/100, which means that 100cg=1g • Deci- 1/10, which means that 10dl=1l • Deka- 10, which means that 1dkm=10m • Hecto- 100, which means that 1hg=100g • Kilo- 1000, which means that 1kl=1000l

11. US Conversions • Length • 1 foot = 12 inches • 1 yard = 3 feet • 1 mile = 5,280 feet

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

13. US Conversions • Weight • 1 lb = 16 oz • 1 ton = 2000 lbs
