Practical Examples of Centimeter to Feet Conversion
To further illustrate the conversion process, consider these examples:
-
Example 1: A table is 150 cm tall. To find its height in feet:
[ \text{Feet} = \frac{150}{30.48} \approx 4.92 ]
So, the table is approximately 4.92 feet tall. -
Example 2: A person’s height is 170 cm. To convert this to feet:
[ \text{Feet} = \frac{170}{30.48} \approx 5.58 ]
Thus, the person is approximately 5 feet 7 inches tall.
