Understanding Inches and Millimeters
What is an Inch?
An inch is a unit of length used primarily in the United States, Canada, and the United Kingdom. It is part of the imperial measurement system and is commonly used to measure small lengths, such as the dimensions of objects, screen sizes, or fabric lengths. Historically, an inch was based on the width of a human thumb, but today it is standardized.
What is a Millimeter?
A millimeter (mm) is a metric unit of length in the International System of Units (SI). It is a very small unit, often used in fields requiring precision such as engineering, manufacturing, and science. One millimeter is equal to one-thousandth of a meter.
