One inch is equivalent to 2.54 centimeters and 25.4 millimeters. Knowing this conversion is crucial when trying to measure lengths that require a different unit from the one you have.

For example, a standard bedroom may be around 12 feet by 15 feet, while an SUV or minivan may be around 15 feet long.
