Step-by-step conversion explanation: To convert 2.54 millimeter to inch, multiply by the conversion factor 0.039370. 2.54 millimeter x 0.039370 = 0.1000 inch.

2.54 millimeter equals exactly 0.100000 inch. For practical purposes, this is often rounded to 0.1000 inch.

Objects measuring approximately 2.54 millimeter include the pin pitch of a standard DIP integrated circuit, the diameter of an M2.5 machine screw, and the thickness of a kettle-cooked potato chip.

Converting millimeter to inch is useful for interoperability in global manufacturing, especially when working with legacy equipment or designs from countries primarily using the imperial system. It is crucial for precision engineering, electronics, and construction to ensure compatibility and accurate specifications.

A simple memory technique is to recall that 25.4 millimeters equals exactly 1 inch. Therefore, 2.54 millimeters is precisely one-tenth of an inch, or 0.1 inch. Visualizing a standard breadboard's pin spacing can also serve as a helpful reference.
