Understanding the Conversion: Centimeters to Feet
What is a centimeter?
A centimeter (cm) is a metric unit of length equal to one-hundredth of a meter. It is widely used around the world for measuring smaller lengths, especially in countries that utilize the metric system.
What is a foot?
A foot (ft) is a customary unit of length primarily used in the United States, United Kingdom, and some other countries. It is equal to 12 inches, and one inch is exactly 2.54 centimeters.
Conversion factor between centimeters and feet
The fundamental conversion between centimeters and feet relies on the following relationships:
- 1 inch = 2.54 centimeters
- 1 foot = 12 inches
Therefore, to convert centimeters to feet, the conversion factor is:
\[ 1 \text{ foot} = 12 \times 2.54 \text{ cm} = 30.48 \text{ cm} \]
This means:
\[ 1 \text{ foot} = 30.48 \text{ cm} \]

Converting 139 cm to Feet
Step-by-step calculation
To convert 139 cm to feet:
1. Divide 139 cm by the number of centimeters in a foot (30.48 cm):
\[ \text{Feet} = \frac{139}{30.48} \]
2. Performing the division:
\[ \text{Feet} \approx 4.56 \]
Thus, 139 centimeters is approximately 4.56 feet.
Expressing in feet and inches
Since decimal feet are less practical for most measurements, it's common to convert the fractional part into inches.
- The decimal part, 0.56, represents a fraction of a foot.
- To convert this to inches:
\[ 0.56 \times 12 = 6.72 \text{ inches} \]
Therefore, 139 cm is approximately 4 feet 6.72 inches.
Rounding to the nearest inch:
- 6.72 inches ≈ 7 inches
So, the measurement can be expressed as:
