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 and lemon


  Pineapple is one order of magnitude larger than lemon
• Dog and woodlouse


  Dog is two orders of magnitude longer than woodlouse
• Order of magnitude


  Every order of magnitude is ten times greater than the one before
• To find the order of magnitude, count the number of zeros
• Calculating order of magnitude difference

  Find how many times larger one object is than the other

  2. Count the number of zeros to determine the order of magnitude difference
