To convert 55 cm to a different unit, we need to determine what unit we want to convert it to. Let’s say we want to convert 55 cm to inches.
1. Start by knowing the conversion factor between centimeters and inches. 1 inch is equal to 2.54 cm.
2. Set up a proportion to solve for the unknown value in inches. The proportion will look like this:
1 inch / 2.54 cm = x inches / 55 cm
3. Cross multiply to solve for x:
2.54 * x = 1 * 55
x = 55 / 2.54
x ≈ 21.65 inches
Therefore, 55 cm is approximately equal to 21.65 inches.
Real-life example:
If you have a ruler that measures in centimeters and you want to know how many inches a 55 cm long object is, you can use the conversion factor to find out that it is approximately 21.65 inches long.
