1. Introduction to the Metric System IT IS SOOOOOOO MUCH EASIER THAN YOU REALIZE!!!!

2. Different ways to measure… What are some of the ways we measure? (3 most common…) Distance Measurement how far it is from one location to another. Volume How much space something takes up. Mass Amount of matter in an object.

3. In the US we use…  Standard system of measurement…  Distance  Point  Pica (1 Pica = 12 Points)  Inch (1 Inch = 6 Picas = 72 Points)  Foot (1 Foot = 12 Inches = 72 Picas = 864 Points)  Yard (1 Yard = 3 Feet = 36 Inches = 216 Picas = 2592 Points)  Mile  = 1760 Yards  = 5280 Feet  = 63,360 Inches  = 380,160 Picas  = 4,561,920 Points

4. In the US we use… Basic Volume… Cubic Volume… Cubic inch Cubic foot Cubic yard Acre-foot Liquid volume… Minim Dram Teaspoon Tablespoon Fluid ounce Shot Gill Cup Pint Quart Gallon Barrel Oil Barrel Hogshead

5. In the US we use…  Weight  Grain  Dram  Ounce  Pound  Hundredweight  Long hundredweight  Ton

6.  Created during French Revolution  in 1790  French King overthrown  National Assembly of France sets up new government  French Academy of Science told to design new system of weights and measures  Lavaiosie appointed to head committee History of Metric System

7. History  Called Systeme International d’Unitès,  or SI - International System of Units  Revised periodically  by International Bureau of Weight and Measures

8. Advantages of Using the Metric System  Simple to use  A few base units make up all measurements  length - meter  mass - grams  volume - liters  temperature – degrees Celsius

9. Advantages of Using the Metric System  There is only one unit of measurement for each type of quantity  To simplify things, very small and very large numbers are expressed as multiples of the base unit.  Prefixes are used to represent how much smaller or larger the quantity is compared to the base unit.  Easy to convert from one unit to another  shift decimal point right  shift decimal point left

10. Advantages of Using the Metric System  Same set of prefixes for all units  Greek - multiples of the base  kilo - 1000 × the base  hecto - 100 × the base  deka - 10 × the base  Latin - fractions of the base  deci - tenths of the base  centi - hundredths of the base  milli - thousandths of the base

11. Metric Prefixes

12. Mnemonics…  K ilo = 1000 (one thousand)  H ecto = 100 (one hundred)  D eka = 10 (ten)  B ase = 1 ( O ne)  D eci =.1 or 1/10 (one tenth)  C enti =.01 or 1/100 (one hundredth)  M illi =.001 or 1/1000 (one thousandth)  Mnemonic: “King Henry Died By Drinking Chocolate Milk”  Mnemonic: “Kids Have Dropped Over Dead Converting Metrics.” NOW YOU COME UP WITH ONE TO HELP YOU REMEMBER!
