Step-by-Step Conversion Process

  1. Start with the length in centimeters that you want to convert. In this case, it’s 4 cm.
  2. Use the conversion factor: 1 inch = 2.54 cm.
  3. Divide the number of centimeters by 2.54 to convert to inches:

    4 cm ÷ 2.54 cm/inch = 1.5748 inches

  4. The result is the equivalent length in inches.
