Conversion Definitions
Inches: An inch is a unit of length in the imperial and US customary measurement systems, equal to exactly 1/12 of a foot or precisely 2.54 centimeters. It often used to measure small to medium length objects, such as screen sizes, heights, or thicknesses.
Millimeters (mm): A millimeter is a metric unit of length equal to one-thousandth of a meter. It is commonly used to measure very small distances or thicknesses, especially in engineering, manufacturing, and science to provide precise measurements.
Conversion FAQs
