About these units
Nail (Cloth) (nail)
The nail is another small unit in cloth measurement, roughly 2.1 cm (0.83 inches), sometimes used interchangeably with the finger in English tailoring. The nail allowed fine precision in textile cutting, marking, and assembly. Its practical relevance lay in breaking down larger units like the yard or ell into smaller, manageable increments suitable for artisans. Though obsolete in modern industry, the nail continues to appear in historical accounts, tailoring manuals, and legal documents concerning cloth trade in England.
Nanometer (nm)
A nanometer—one billionth of a meter (10⁻⁹ m)—is central to nanoscience, nanotechnology, and molecular biology. Many structures essential to life fall into this scale: DNA's double helix is about 2 nm wide, viruses often measure tens to hundreds of nanometers, and key cell structures like ribosomes are on the order of 20–30 nm. In engineering, nanometers define the dimensions of modern semiconductor technology. Silicon transistors have shrunk to features only a few nanometers wide, approaching the physical limits of electron behavior in solid-state materials. In optics, wavelengths of ultraviolet light can be expressed in nanometers, as can surface roughness, material grain sizes, and thin-film coatings. The nanometer is ubiquitous across modern science because it describes both biological and technological structures at the frontier of research.
