To convert 3 cm to a different unit, we need to know the conversion factor between centimeters and the desired unit. Let’s say we want to convert 3 cm to inches.
1. Determine the conversion factor between centimeters and inches. 1 inch is equal to 2.54 centimeters.
2. Set up a proportion to convert 3 cm to inches:
3 cm = x inches
1 inch = 2.54 cm
3. Cross multiply and solve for x:
3 * 1 = 2.54 * x
3 = 2.54x
x = 3 / 2.54
x ≈ 1.18 inches
Therefore, 3 cm is approximately equal to 1.18 inches.
Real-life example:
If you have a ruler that measures in centimeters and you want to know how many inches a 3 cm long object is, you can use the conversion factor to find out that it is approximately 1.18 inches long.
