Even though Canada switched over to the metric system in the 1970's, we still use a number of Imperial measurements.  You just need to think about some of the ways that we measure different things like height or weight.  Many lenghts of lumber are still measured in imperial units as well.


  • Notes: Imperial Units


  • p29 #2, 3, 5, 7, 8, 9, 10, 11, 15, 16, *17 *18

Things you should be able to do after today:

  • convert imperial units using conversion factors
  • read an imperial caliper
  • read a ruler or measuring device that uses imperial units (with fractions)
