To convert centimeters (cm) to inches (in), we use the following conversion factor:
1 cm=0.393701
So, to convert 4 cm to inches, we multiply 4 by the conversion factor:
4 cm×0.393701
Thus, 4 cm is approximately equal to 1.575 inches.
Understanding the Conversion
The centimeter is a metric unit of length used widely around the world, especially in countries using the metric system. The inch, on the other hand, is part of the Imperial system, commonly used in the United States and the United Kingdom. The conversion factor of 1 cm = 0.393701 inches comes from the relationship between the metric system and Imperial measurements.
Practical Application
For example, if you have an object that is 4 cm long and need to convert that to inches for a project, you can use the above formula. Knowing this conversion is especially helpful when dealing with small measurements, such as the size of a phone screen, fabric measurements, or precise tool lengths, which are often provided in either centimeters or inches depending on the country or industry.
