To convert 3.5 cm to inches, we need to use the conversion factor 1 inch = 2.54 cm.
Step 1: Write down the given measurement
We have 3.5 cm as the given measurement.
Step 2: Set up the conversion factor
As mentioned above, we will use the conversion factor 1 inch = 2.54 cm. To set up the conversion, we will write it as a fraction: 1 inch / 2.54 cm.
Step 3: Set up the equation
Now, we need to set up the equation as follows:
3.5 cm x (1 inch / 2.54 cm)
Step 4: Simplify the equation
We can simplify the equation by canceling out the unit cm, leaving us with:
3.5 x 1 inch / 2.54
Step 5: Calculate the value
Using a calculator, we can multiply 3.5 and 1 to get 3.5. Then, we will divide 3.5 by 2.54 to get the final answer: 1.37795 inches.
Step 6: Round off the answer (optional)
In most cases, we will need to round off the answer to the appropriate number of decimal places. Since inches is a unit of length, we can round off the answer to 2 decimal places, giving us 1.38 inches.
Therefore, 3.5 cm is equal to 1.38 inches.
