Convert Centimeters To Feet And Inches: The Ultimate Guide To Height Conversion
Converting centimeters to feet and inches is a common need for many people, whether you're traveling internationally, comparing heights, or shopping for clothes. This comprehensive guide will walk you through everything you need to know about converting cm to ft, including the formula, examples, and the best tools available.
Understanding Centimeters and Feet
Before diving into conversions, it's important to understand the difference between centimeters and feet. Centimeters are part of the metric system, widely used around the world for scientific measurements and everyday applications. Feet, on the other hand, are part of the imperial system, primarily used in the United States, United Kingdom, and a few other countries.
How many feet in a centimeter? There are 0.0328084 feet in one centimeter. Conversely, one foot equals 30.48 centimeters. This conversion factor is the key to converting between these two units of measurement.
The Formula for Converting cm to Feet
To convert cm to feet, you can use a simple formula:
Feet = Centimeters ÷ 30.48 For example, if you want to convert 170 centimeters to feet:
170 ÷ 30.48 = 5.577 feet This gives you the measurement in decimal feet. However, for height measurements, we often want to express this in feet and inches.
Converting Centimeters to Feet and Inches
To convert centimeters to feet and inches, follow these steps:
- Divide the centimeters by 30.48 to get the total feet in decimal form
- Take the whole number part as the feet measurement
- Multiply the decimal part by 12 to convert it to inches
Let's use our 170 cm example:
- 170 ÷ 30.48 = 5.577 feet
- The whole number part is 5 feet
- 0.577 × 12 = 6.92 inches (rounded to 7 inches)
Therefore, 170 cm equals 5 feet 7 inches.
