Converting units of length can be a simple and useful skill in everyday life. In this case, we are going to convert 7.5cm to inches. To do this, we will use a conversion factor, which is a numerical relationship between the two units.
Step 1: Understand the conversion factor
In this case, the conversion factor between centimeters (cm) and inches (in) is 1 inch = 2.54 centimeters. This means that for every 1 inch, there are 2.54 centimeters.
Step 2: Write down the given value
In this case, our given value is 7.5cm.
Step 3: Set up the conversion equation
To convert between units, we can use the equation:
(original value) x (conversion factor) = (converted value)
Step 4: Plug in the values
Using the conversion factor, we can set up our equation as:
7.5cm x (1 in/2.54 cm) = (converted value)
Step 5: Cancel out the units
The unit “cm” cancels out leaving us with:
7.5 x (1 in/2.54) = (converted value)
Step 6: Solve for the converted value
Using a calculator, we can solve this equation to get our converted value of 2.95 inches.
Step 7: Round the answer
Since we are dealing with a length measurement, it is appropriate to round our answer to two decimal places. Therefore, our final answer is 2.95 inches.
In summary, to convert 7.5cm to inches, we used the conversion factor of 1 inch = 2.54 centimeters and followed the steps outlined above. Remember, understanding the conversion factor and properly setting up the conversion equation is key to successfully converting units of length.
