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.
Yard (yd)
Definition: A yard (yd) is a unit of length equal to 0.9144 meters or three feet. It is commonly used in construction, sports fields, and textile measurements, particularly in the US and UK.
History: The yard originated in medieval England, standardized by King Henry I. It was originally based on the length of a man's belt or the distance from the nose to the thumb tip.
Current Use: Yards are widely used in the US and UK for measuring land, fabric, and sports fields, including American football. They are also commonly seen in real estate and landscaping measurements.
