What are Feet and Inches?
Feet and inches are units of measurement primarily used in the imperial system. Widely adopted in the United States, these units are often employed to measure height, length, and distance. A foot is symbolized as ft, while an inch is denoted as in. To provide context, 1 foot is equivalent to 12 inches, and both units are commonly used together for more precise measurements.
The origins of feet and inches date back to ancient civilizations where body parts served as measuring tools. The word "foot" was derived from the average length of a human foot, whereas an inch was based on the width of a thumb. Although these measurements have since been standardized, their historical roots remain fascinating.
How do feet and inches work together?
When measuring objects or people, feet and inches are often combined for clarity. For instance, a person's height might be described as 5 feet 8 inches, written as 5'8". This combination provides a more precise measurement than using only feet or inches individually.
What is a Centimeter?
A centimeter, abbreviated as cm, is a unit of length in the metric system. It is widely used across the globe, particularly in countries that have adopted the metric system. The centimeter is part of the International System of Units (SI) and is defined as one-hundredth of a meter. To put it simply, 1 cm equals 0.01 meters.
Unlike feet and inches, which are based on historical measurements, the centimeter is derived from the meter—a unit established during the French Revolution to bring uniformity to measurements. This precision makes the metric system highly reliable and universally accepted.
How does a centimeter compare to inches?
To understand the relationship between centimeters and inches, it's important to note that 1 inch is approximately equal to 2.54 cm. This conversion factor is crucial when switching between imperial and metric systems.

How to Convert Feet and Inches to cm?
Converting feet and inches to cm involves a straightforward process. The key is to break the measurement into two parts—feet and inches—and convert each separately before adding them together. Here's a step-by-step guide:
- Convert feet to cm: Multiply the number of feet by 30.48 (since 1 foot = 30.48 cm).
- Convert inches to cm: Multiply the number of inches by 2.54 (since 1 inch = 2.54 cm).
- Add the results from steps 1 and 2 to get the total measurement in cm.
For example, to convert 5'8" to cm:
- Convert 5 feet to cm: 5 × 30.48 = 152.4 cm
- Convert 8 inches to cm: 8 × 2.54 = 20.32 cm
- Add the two results: 152.4 + 20.32 = 172.72 cm
Thus, 5'8" is equal to 172.72 cm.
Simple Formula for Conversion
If you're looking for a quick formula, here it is: Total cm = (Feet × 30.48) + (Inches × 2.54)
This formula works universally, whether you're converting measurements for a project, a recipe, or personal records.
