About Angstroms
An angstrom (Å) is equal to 0.1 nanometers or 10⁻¹⁰ meters, named after Swedish physicist Anders Jonas Ångström. While not an official SI unit, it remains widely used in chemistry, solid-state physics, and crystallography to express atomic distances and wavelengths. A typical atom has a diameter of 1-3 angstroms, and the spacing between atoms in crystals is commonly measured in angstroms. X-ray crystallographers use angstroms to describe molecular structures with atomic precision.
About Thou
A thou (also called mil) is one thousandth of an inch, equal to 0.0254 millimeters or 25.4 micrometers. This unit is commonly used in engineering and manufacturing in countries that use imperial measurements, particularly for specifying tolerances, wire gauges, and thin material thicknesses. For example, a standard plastic bag might be 1-2 thou thick, a sheet of paper is about 4 thou, and precision machined parts often have tolerances measured in thou. Electronic circuit board copper traces are typically 1.4 thou thick.
