Metric Measures

  1. 1. Measurement & Graphing
  2. 2. Standards of MeasurementStandard – exact quantity that people agree to use for comparisonMetric System – system of measurement based on multiples of 10SI – International System of Units used and accepted worldwide
  3. 3. Common SI PrefixesPrefix Symbol Multiplying Factordeka- D 10 = 101hecto- H 100 = 102kilo- k 1000 = 103deci- d 0.1 = 10-1centi- c 0.01 = 10-2milli- m 0.001 = 10-3micro- μ 0.000001 = 10-6nano- n 0.000000001 = 10-9
  4. 4. Using SI UnitsQuantity Unit SymbolMeasuredLength Meter mMass Kilogram kgTime Second sElectric Current Ampere ATemperature Kelvin KAmount of Mole molsubstanceIntensity of light Candela cd
  5. 5. Temperature Kelvin  Celsius 273K = Freezing  0˚C = Freezing 373K = Boiling  100˚C = Boiling Coldest Possible Temp:  ˚C = K – 273  Absolute 0 = -273˚C K=˚C + 273
  6. 6. Try these temp. conversions: 98.6 º C = ? K 104.38 K = ? º C
  7. 7. Conversion Tips A measurement consists of two parts:  a number and  a unit label To convert from larger to smaller units:  Multiply or  MOVE DECIMAL TO THE RIGHT To convert from smaller to larger units:  Divide or  MOVE DECIMAL TO THE LEFT
  8. 8. Use this Tool:Kilo Hecto Deka Meter (m) Deci Centi Milli(k) (h) (D) Gram (g) (d) (c) (m) Liter (L)
  9. 9. Try these conversions: 1 km = _____________ m 1 m = _____________ cm 25 km = ________ m = _______ cm 55 kL = _______ cL = ________ L
  10. 10. Graphing Graph – a visual display of information or dataUses of Graphs Line Graphs – show trends or how data change over time Bar Graphs – compare information collected by counting Circle (Pie) Graphs – show how a fixed quantity is broken down into parts.
