Units, Dimensional Analysis, and Conversion Factors: Summary

The answers to the ConcepTests are given below and will open in a separate window. 
Key points from this module:
  • A quantity means nothing without its respective engineering unit!
  • Always carry units along with quantities, and perform dimensional analysis.
From studying this module, you should now be able to:
  • Define a quantity as having both a numerical value and units.
  • Use dimensional analysis to verify that equations have consistent units.
  • Convert units.
