(I'm very sorry, this picture has a typo, the 0.492701 In. should be 0.393701 In. I'm very sorry for this inconvience).

  • Since we are doing a conversion factor, a unit has to be cancelled out. In this example, it is centimeters. We now, simply multiply across and solve for the answer in inches. Since we have a decimal, the number will be smaller.

Answer - 21 Inches.
