Historical Context and Significance
The inch, an integral part of the imperial measurement system, is commonly used in the United States and some other countries. Its origin is often attributed to the width of a human thumb. The centimeter, a unit in the metric system, is onehundredth of a meter and is widely used globally for a variety of measurements.
Conversion Formula
The formula to convert inches to centimeters is:
$$ \text{Centimeters} = \text{Inches} \times 2.54 $$
This formula is based on the standard conversion factor where one inch is equal to 2.54 centimeters.
Example Calculation
Let's convert 10 inches to centimeters.
Using the formula: $$ \text{Centimeters} = 10 \times 2.54 = 25.4 \text{ cm} $$
So, 10 inches is equal to 25.4 centimeters.
