Length conversion is the process of changing a measurement from one unit to another. Common units of length include meters, centimeters, inches, and feet. For example, to convert inches to centimeters, you can multiply the number of inches by 2.54, since one inch is equal to 2.54 centimeters. To perform length conversions, it is essential to know the relationship between different units. For instance, there are 100 centimeters in a meter and 12 inches in a foot. Using these relationships, you can easily convert measurements to suit your needs, whether for construction, crafting, or everyday tasks.
