History

Nanometer (nm)

The nanometer, symbolized as nm, equals one billionth of a meter and is vital in nanotechnology, physics, and chemistry. It was first defined with the development of atomic-scale research in the 20th century. Nanometers are used to measure light wavelengths, semiconductor features, and molecules, playing a crucial role in electronics, optics, and biotechnology. The unit exemplifies the precision and scalability of the metric system, enabling scientists and engineers to explore dimensions at the atomic and molecular levels. Its adoption has revolutionized modern technology and scientific understanding.

Inch (in)

The inch, abbreviated as in, is a length unit in the imperial and US customary systems. Its history reaches back to ancient civilizations, including the Romans, Egyptians, and Anglo-Saxons. Originally, the inch was determined by the width of a human thumb, but it was eventually set as 1/12 of a foot. Since 1959, the inch has been officially defined as exactly 2.54 centimeters due to an international agreement. Inches are still widely used in the United States, Canada, and the UK, especially for construction, manufacturing, and personal measurements. Even with the global shift to metric units, the inch remains important in certain fields such as technical drawings, screen dimensions, and household tools.
