  1. METRICS

  2. Measurements are relative!! • Foot = human foot • Inch = 3 barley corns • Yard = nose to outstretched fingertip • Mile = 1,000 paces • Gallon = simply the name for a pail

  3. Why is there a need for one system of measurement? • Universal acceptance • Accurate measurement

  4. Do you know our current system? • How many inches in a foot? • How many feet in a yard? • How many feet in a mile? • How many ounces in a cup? • How many cups in pint? • How many pints in a quart?

  5. Le Systeme International d’Unites SI

  6. 7 Standard Metric Base Units • Unit of length (metre) • Unit of mass (kilogram) • Unit of temperature (kelvin) • Unit of time (second) • Unit of electric current (ampere) • Unit of amount of substance (mole) • Unit of luminous intensity (candela)

  7. Measurements • Length (m) • Mass (kg) • Volume (L) • Temperature (K or C) • Time (s)

  8. English to Metric conversions • 1 gallon = 3.78 liters • 1 pound = 453 grams • 1 inch = 2.54 centimeters • 1 foot = .3048 meters • 1 yard = .91 meters • 1 mile = 1, 609 meters •  1 tsp = 5 ml

  9. Length Analogies • 1 km = 5 city blocks (8 blocks = 1 mile) • 1 hm = little longer than a football field  • 1 dam= about the height of a 3-story building • 1 m = length of a baseball bat or golf club • 1 dm = nearly the length of a crayon • 1 cm = width of little finger / pencil • 1 mm = thickness of an ID card

  10. Mass Analogies • 1 kg = 2.2 lbs = approx. weight of textbook • 1 hg = thin razor cell phone • 1dag = 2 nickels • 1 g = weight of a small paperclip • 1dg = toothpick • 1cg = adult housefly • 1 mg = weight of a piece of dust

  11. Volume Analogies • 1 kl = large aquarium • 1 hl = helium tank • 1 dal = medium-sized bucket • 1 L = water bottle • 1 dl = small-sized hair products • 1 cl = • 1 ml = single drop of liquid / teardrop

  12. Temperature Analogies Celsius memory aid: When it's zero it's freezing,when it's 10 it's not,when it's 20 it's warm,when it's 30 it's hot!

  13. Metric Conversions

  14. Kilo Big prefix Means- Times 1000

  15. Hecto Big prefix Means- Times 100

  16. Deka Big prefix Means- Times 10

  17. X This is where the root of each prefix is. This is one. 1 gram (g) – 1 meter (m) – 1 Liter (L)

  18. Deci Small prefix Means- Divided by 10

  19. Centi Small prefix Means- Divided by100

  20. Milli Small prefix Means- Divided by1000
