CM to Feet Converter
Centimeter (cm)
The centimeter (cm) is a unit of length in the metric system, equal to one hundredth of a meter. It is part of the International System of Units (SI).
Historically, the metric system was first proposed in 1670 by Gabriel Mouton, a French vicar and scientist, with the meter defined as one ten-millionth of the distance from the North Pole to the Equator. The centimeter naturally derived from this definition as a convenient smaller unit.
Today, centimeters are widely used globally for various measurements, especially in fields like:
- Everyday Measurements: Measuring objects, fabric, or body dimensions.
- Science and Engineering: Used in laboratory settings, blueprints, and small-scale designs.
- Medical Field: For measuring patient's height, wound sizes, or organ dimensions.
- Education: Taught as a fundamental unit of length in schools worldwide.
Its ease of use, due to its base-10 nature, makes it a popular unit in countries that have adopted the metric system.
Foot (ft)
The foot (plural: feet; abbreviation: ft or ′) is a unit of length in the imperial and U.S. customary systems of measurement. It is defined as exactly 0.3048 meters.
The history of the foot as a unit of measurement is long and varied, with its origins often traced back to ancient civilizations. It was originally based on the length of a human foot, though its exact length varied significantly across different regions and times.
Some historical references include:
- Ancient Egypt: Used a "royal cubit" and other foot-like measures.
- Ancient Greece and Rome: Had their own versions of the foot. The Roman foot (pes) was approximately 29.6 cm.
- Medieval Europe: Various local feet were in use.
- British Empire: The modern international foot (0.3048 meters) largely derived from the British system, which was standardized over centuries.
Today, the foot is primarily used in the United States, Canada, and the United Kingdom (informally) for applications such as:
- Height: Measuring people's height (e.g., 5 feet 10 inches).
- Altitude and Aviation: Used for aircraft altitude and elevation.
- Construction: Common in building and surveying.
- Sports: Dimensions of sports fields and events.

How to Convert Centimeters to Feet
To convert a measurement in centimeters (cm) to feet (ft), you can use the following formula:
Conversion Formula:
Feet = Centimeters × 0.0328084
This is because 1 centimeter is approximately equal to 0.0328084 feet.
Example:
Let's convert 150 cm to feet:
Feet = 150 cm × 0.0328084 = 4.92126 ft
So, 150 centimeters is approximately 4.92126 feet.
Important Notes on CM to Feet Conversion
Considerations:
- The conversion factor
0.0328084is an approximation. For more precise calculations, you might use more decimal places (e.g., 0.03280839895 feet per centimeter). - Sometimes, feet measurements are expressed in feet and inches (e.g., 5 feet 6 inches). To convert a decimal foot value to feet and inches, multiply the fractional part of the foot by 12. For example, 4.92126 feet is 4 feet and
0.92126 × 12 = 11.05512inches, so approximately 4 feet 11 inches. - The imperial system (which includes feet) is non-decimal, which can sometimes make conversions and calculations more complex compared to the metric system's base-10 nature.
- When performing conversions for practical applications like construction or manufacturing, always consider the required precision and significant figures.
