Converting units of length can seem daunting at first, but it is actually quite simple. In this case, we are tasked with converting 2.5 cm (centimeters) to inches. The basic idea is to use a conversion factor, which is a numerical relationship between the two units. In this case, the conversion factor between centimeters and inches is 1 inch = approximately 2.54 centimeters.
To convert 2.5 cm to inches, we will use the following steps:
Step 1: Write down the given value.
2.5 cm
Step 2: Write down the conversion factor.
1 inch ≈ 2.54 cm
Step 3: Set up the conversion equation, with the given value on one side of the equation and the conversion factor on the other side.
2.5 cm = ? inches
1 inch ≈ 2.54 cm
Step 4: Multiply the given value by the conversion factor.
2.5 cm x 1 inch ≈ 2.54 cm = 2.5 inches ≈ 6.35 cm
Step 5: Cancel out the units that are the same on both sides of the equation (cm in this case).
2.5 inches ≈ 6.35 cm
Step 6: Round the answer to the appropriate number of significant figures. In this case, we are converting to inches, so we will round to the nearest hundredth.
2.5 inches ≈ 6.35 cm ≈ 2.54 inches
Therefore, 2.5 cm is approximately 1 inch. You can double check by converting back to centimeters using the same steps. Just make sure to use the inverse of the conversion factor (2.54 cm = 1 inch) and you should get 2.5 cm as your answer.
In conclusion, converting units of length can be done easily by using a conversion factor and following the steps outlined above. With some practice, you’ll be able to convert between any units of length with ease.
