About these units
League (Statute) (st.league)
The statute league was historically defined as 3 statute miles (~4.828 km). It originated as a measure of distance a person could travel on foot in about an hour. Leagues were widely used in exploration, mapping, and maritime navigation prior to the universal adoption of standardized miles and kilometers. They also appear extensively in literature, conveying narrative distances in a way more relatable to the human scale. Though obsolete in modern usage, the statute league provides cultural and historical context for maps, journals, and records from the 16th through 19th centuries.
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.
