Basic Concepts of Measurement Units
What is a Centimeter?
The centimeter (cm) is a metric unit of length. It is part of the International System of Units (SI) and is commonly used worldwide for everyday measurements. One centimeter equals one-hundredth of a meter, making it a convenient unit for measuring small to moderate lengths.
What is a Foot?
The foot (ft) is a unit of length traditionally used in the United States and other countries that employ the imperial system. It is larger than a centimeter and is often used for measuring height, room dimensions, or other larger objects. One foot equals 12 inches, and its metric equivalent is approximately 0.3048 meters.
Conversion Factors and Formulas
The Standard Conversion Rate
The key to converting centimeters to feet is knowing the conversion factor:
- 1 foot = 30.48 centimeters
Therefore, to convert centimeters to feet, divide the length value in centimeters by 30.48.
Conversion Formula
Feet = Centimeters ÷ 30.48
Converting 45 cm to Feet

So, 45 centimeters is approximately 1.476 feet. For simplicity, this can be rounded to 1.48 feet or expressed as 1 foot and 5.7 inches.
Expressing 45 cm in Feet and Inches
Why Express in Feet and Inches?

Conversion Process
- Start with the decimal feet: 1.4764 ft
- Extract the whole number: 1 foot
- Convert the fractional part (0.4764 ft) into inches:
- Since 1 foot = 12 inches, multiply 0.4764 by 12
