Understanding the Conversion between Centimeters and Feet
What is a Centimeter?
A centimeter (cm) is a metric unit of length equal to one hundredth of a meter. It is commonly used worldwide for measuring height, length, and distance in everyday life, especially in countries that utilize the metric system.
What is a Foot?
A foot (ft) is an imperial and US customary unit of length. It is traditionally used in the United States, the United Kingdom, and some other countries. One foot equals 12 inches, and an inch is 2.54 centimeters.
Basic Conversion Relationship
The fundamental relationship for converting centimeters to feet involves the following:
- 1 foot = 12 inches
- 1 inch = 2.54 centimeters
- Therefore, 1 foot = 12 × 2.54 cm = 30.48 cm
This means that:

How to Convert 171cm to Feet
Step-by-Step Conversion Process
To convert centimeters to feet, follow these steps:
1. Divide the centimeter measurement by 30.48:
\[
\text{Feet} = \frac{\text{Centimeters}}{30.48}
\]
2. Calculate for 171 cm:
\[
\text{Feet} = \frac{171}{30.48} \approx 5.607
\]
3. Interpret the result:
- The total feet are approximately 5.607 feet.
- To express this in feet and inches, take the decimal part (0.607) and convert it to inches.
Converting the Decimal Part to Inches
Since 1 foot = 12 inches:
\[
0.607 \times 12 \approx 7.28 \text{ inches}
\]
Rounding to the nearest inch:
\[
7.28 \text{ inches} \approx 7 \text{ inches}
\]
Therefore, 171 cm is approximately 5 feet 7 inches.
