To convert from centimeters (cm) to inches (in), we must first know the conversion factor between the two units. The conversion factor for cm to in is 1 cm = 0.393701 in. This means that for every 1 cm, there are 0.393701 inches.
To convert 140 cm to inches, we will use this conversion factor and follow these steps:
Step 1: Write down the known value in cm.
We know that 140 cm is the value that needs to be converted.
Step 2: Set up the conversion equation.
We will use the conversion factor mentioned above to set up the equation. It will look like this:
140 cm x (0.393701 in/ 1 cm)
Step 3: Cancel out the unit that appears both in the numerator and the denominator.
We can cancel out the unit cm in the numerator and the denominator since it appears on both sides of the fraction.
140 x (0.393701 in/ 1)
= 140 x 0.393701 in
= 55.11814 in
Step 4: Round off the result.
The final answer is 55.11814 in. However, this may be more precise than needed in most cases, so we can round it off to a more manageable number. The general rule for rounding off is to look at the next digit after the desired number of decimal places and increase the desired number by 1 if that digit is 5 or more. Since the next digit after the hundredths place is a 1, we will keep the value at the hundredths place as 8.
Finally, our answer is:
140 cm = 55.12 in
And that’s it! You have successfully converted 140 cm to inches. Remember to always double-check your conversion by using a calculator or an online converter to ensure accuracy.
