Millimeter

A millimeter (mm) is a very small unit of length in the metric system. It is commonly used to measure tiny objects or precise dimensions. One millimeter is equal to one-thousandth of a meter (1 mm = 0.001 m), and 10 millimeters make 1 centimeter. Millimeters are often used in fields like engineering, machining, and science where exact measurements are important. For example, the thickness of a credit card is about 1 mm. The symbol for millimeter is "mm", and you can find it on most rulers or measuring tools. Since it allows for high accuracy, the millimeter is ideal for measuring small parts, gaps, or details.

Micron

A micron is another name for a micrometer, a very small unit of length in the metric system. One micron equals one-millionth of a meter (1 micron = 1 µm = 0.000001 meters). Microns are used to measure extremely small things like bacteria, cells, dust particles, or the thickness of hair and fibers. For example, a human hair is about 70 microns thick. The symbol for micron is "µm". Though “micron” is an older term, it is still commonly used in fields like biology, electronics, and materials science to describe microscopic measurements.
