Micrometer (µm)
Definition: A micrometer (µm) is one-millionth of a meter. It is commonly used to measure microscopic objects like bacteria, thin film thickness, and components in precision engineering.
History: With the advancement of microscopy and material sciences, the micrometer became essential for measuring extremely small objects. It is a key unit in nanotechnology and microfabrication industries.
Current Use: Micrometers are widely used in microbiology, physics, and semiconductor industries. They help measure cell sizes, fiber diameters, and thin material layers used in optical lenses and medical devices.
Meter (m)
Definition: The meter (m) is the base unit of length in the International System of Units (SI), defined by the speed of light in a vacuum. One meter is the distance light travels in 1/299,792,458 of a second.
History: The meter was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole. It has since been redefined multiple times, most recently in 1983 using the speed of light.
Current Use: The meter is universally used in science, engineering, and daily life for measuring objects, distances, and heights. It is the foundation of the metric system and adopted by nearly every country worldwide.
