3. 3. Why?everyone else doeseasy to use ( if you grew up with it- based on units of 10) 1m = 10 dm = 100cm = 1000mm x10 x10 x10
4. 4. Known as SI system systeme internationalePrefixes indicate the multiple of 10 kilo= 1000 x 1000m=1kilometer deci= 1/10th 1m=10dm centi= 1/100th 1m=100cm milli= 1/1000th 1m =1000mm
5. 5. Standardsexact quantity people agree to use for comparison Length- distance between 2 points: meter Volume- amount of space an object occupies: liter Mass- amount of matter in an object: kilogram Time- seconds Temperature- celsius or kelvin
6. 6. Derived unitsThese are units obtained by combining different SI units. example: density- mass/volume so g/mL or Kg/L speed: m/sec or km/hr
7. 7. Double-click to enter title This rock- diameter of 10 cm (length) volume of 650mL (space) mass of 2.2kg (matter) | | density of 3.38g/mL
8. 8. Match- measurement to property Volume .99 g/ml Mass 128mL density .128kg height 25 C temperature 9 cm
