Converting measurements between the metric system and the imperial system is a common task, especially when dealing with lengths such as centimeters (cm) to inches (in). To understand this conversion, it's essential to know the relationship between these two units. The metric system, used in most countries, is based on the meter, while the imperial system, commonly used in the United States, relies on the inch for measurements less than a foot.
Understanding the Conversion Factor
The conversion factor between centimeters and inches is derived from the fact that 1 inch equals 2.54 centimeters. This conversion factor allows for the straightforward conversion of lengths between the two systems. To convert centimeters to inches, you divide the number of centimeters by 2.54.
Converting 20 cm to Inches
To convert 20 cm to inches, you apply the conversion factor directly. The calculation is as follows: 20 cm divided by 2.54 cm/in equals approximately 7.874 inches. This means that 20 centimeters is equivalent to about 7.874 inches.
| Measurement in cm | Equivalent in Inches |
|---|---|
