  1. Metric System Connections and Why We Use It

  2. Before Metric Subjective, Variable and Confusing

  3. Volume • 3 teaspoons = 1 tablespoon • 3 tablespoons = a jigger • 2 tablespoons is 1 fluid ounce • 8 fluid ounces = 1 cup • 2 cups = 1 pint • 2 pints = 1 quart • 4 quarts = 1 gallon • 55 gallons = 1 barrel of oil • 63 gallons = 1 hogshead

  4. Length: Distance METER

  5. Volume: How Much Something Holds LITER

  6. Mass KILOGRAM

  7. Temperature KELVINS

  8. Time SECOND

  9. Metric Basics to Remember

  10. French Republic Adopts Metric: 1791

  11. French Revolution Ideals • Liberty • Fraternity • Equality The metric system was not based on kings or trade guilds, or used archaic and seemingly random conversion numbers, but on the Earth and a ten base.

  12. How They Got the Meter Distance from equator to pole. Divide by 10,000 One meter

  13. Current Meter Definition • "the length of the path travelled by light in vacuum during a time interval of 1/299,792,458 of a second."

  14. How Length Becomes Volume 0.1 meter 0.1 meter 0.1 meter

  15. 1 Liter 0.1 meter 0.1 meter 0.1 meter

  16. How Volume Becomes Mass

  17. 1 Kilogram

  18. Kilogram

  19. Relationship 0.1 cubic meter =1 liter 1 liter = 1 kilogram of water 1 kilogram of water = 0.1 cubic meter 0.1 cubic meter….

  20. 1 g = 1 cm^3 = 1ml

  21. Length • 10 millimeters = 1 centimeter • 10 centimeters = 1 decimeter • 10 decimeters = 1 meter • 10 meters = 1 decameter • 10 decameters = 1 heptameter • 10 heptameters = 1 kilometer

  22. 1 Meter • 1000 millimeters • 100 centimeters • 10 decimeters • 1 meter • 0.1 decameters • 0.01 heptameters • 0.001 kilometer

  23. Words Having Meaning (in Latin) • Milli = one thousandth • Centi = one-hundreth • Deci = one-tenth • Meter = Measure • Deca = ten • Hepto = one hundred • Kilo = one thousand

  24. Temperature • 0 Kelvin = Absolute Zero – The coldest possible temperature • Celsius + 273.15 = Kelvin • Celsius/Centigrade • 100 Water Boils • 0 Water Freezes • Each degree is 1/100th from boiling to freezing

  25. Practice Questions • 1000mg = _____ g • 50 cm = ______ m • 480cm = ______m • 5.6 kg = _______ g • 8 mm = _______ cm • 273.15 Kelvin = ______ Celsius • A jar is 30 cm long, 40 cm wide, and 50 cm high. How much water does it hold in liters • Would you rather have 1 kilodollar or 1001 dollars?

  26. Acronym kids-kilo have-hecto dropped-deca Over------ dead-deci converting-centi metrics-milli

  27. Scientific Notation • Multiply by 10^x to get the correct power • Do these problems in Scientific Notation • 1000mg = _____ g • 50 cm = ______ m • 480cm = ______m • 5.6 kg = _______ g • 8 mm = _______ m

  28. Put Away Papers • Ask any last minute questions of your teacher • 1000 milli(meters) (grams) (liters) • 100 centimeters • 10 decimeters • 1 meter • 0.1 decameters • 0.01 heptameters • 0.001 kilometer
