About these units
Furlong (US Survey) (fur (US))
The US Survey Furlong is defined as 660 US Survey Feet (~201.168 meters), exactly 10 US survey chains. It was historically used in land measurement, agriculture, and railroads. Furlongs remain relevant for interpreting historical property layouts and land grants, particularly in rural and agricultural contexts. The unit's convenience derives from its direct relationship with the acre and chain, facilitating rapid calculation of large land areas. While the furlong is largely obsolete in modern measurement, it persists in legal and historical survey references, bridging imperial traditions and contemporary land-use documentation.
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.
