To convert 3.0 cm to a different unit, we need to understand the relationship between centimeters and the unit we want to convert to. In this case, let’s convert 3.0 cm to inches.
1. Start by knowing the conversion factor between centimeters and inches. 1 inch is equal to 2.54 centimeters.
2. Set up a proportion to convert 3.0 cm to inches:
3.0 cm = x inches
1 inch = 2.54 cm
3. Cross multiply to solve for x:
3.0 cm * 1 inch = x inches * 2.54 cm
3.0 = 2.54x
x = 3.0 / 2.54
x ≈ 1.18 inches
Therefore, 3.0 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 3.0 cm object is, you can use the conversion factor to find out that it is approximately 1.18 inches long.
