title: Unit Conversions! Ghz - ns - MHz - cycles
body: <p>I am preparing for a units quiz and there are two kinds of conversions that have me stumped. </p>
  
  <p>Type one:
  What is length (in ns) of one cycle on a XXX computer?
   - In this case, XXX can be some MHz or Ghz, randomly. I am having trouble converting the cyles times. Example:</p>
  
  <p>What is length (in ns) of one cycle on a 50 MegaHertz (MHz) computer?</p>
  
  <p>The second type of conversion I have trouble with:
  If the average instruction on a XXX computer requires ZZ cycles, how long (in ns) does the average instruction take to execute?
   - Like the previous case, the XXX will either be some MHz or Ghz. For example:</p>
  
  <p>If the average instruction on a 2.0 GigaHertz (GHz) computer requires 2.0 cycles, how long (in ns) does the average instruction take to execute?</p>
  
  <p>I don't understand what I am doing wrong in these conversions but I keep getting them wrong. Any help would be great!</p>
