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.
Inch (in)
Definition: An inch (in) is an imperial unit of length equal to 1/12 of a foot or 2.54 centimeters. It is commonly used for measuring small distances and screen sizes.
History: The inch was originally based on the width of a human thumb. It was later standardized in the 14th century by King Edward II of England as three barleycorns placed end to end.
Current Use: Inches are widely used in the US, UK, and Canada for measuring screen sizes, furniture dimensions, and industrial tools. It remains a popular unit in carpentry, printing, and manufacturing.
