Order of Magnitude

• Order of magnitude


  A way to compare the approximate size of different objects
• Objects of the same order of magnitude

  • Apple and orange
• Pineapple compared to lemon

  Pineapple is around 10 times larger, so it is 1 order of magnitude larger
• Dog compared to woodlouse

  Dog is around 100 times longer, so it is 2 orders of magnitude longer
• How to determine order of magnitude

  Count the number of zeros - each zero represents 1 order of magnitude
• Calculating order of magnitude difference

  Divide the larger measurement by the smaller measurement

  2. The number of orders of magnitude is the number of zeros in the result
